Schottky Junction and Ohmic Contacts

[@drraghunath83]

Came for Schottky barrier, sat for the full lecture. Thank you sir!

[@dr.banwarilalchoudhary2564]

Prof. M.R.Shenoy explained very simple language , I like this type of teaching . he explained like Prof H.C.Verma.

[@mariagoryacheva4141]

I ended up watching all his lectures! Simple yet so informative!

[@sandipsatpathi7959]

He is the best

[@mohamedbelkahla6187]

i'm from Tunisia and i like to thank u alot for your explanation .. pls come to tunisia and teach our teachers how to teach .

[@uncleroq]

hahahahaha broooo u jus killled me. hahahahaha

This teacher can make someone pursue a PhD in semiconductor physics! Simply amazing teaching. Thank you.

[@spoilereleven231]

One of the best teachers I have encountered.

[@sushilkumar5606]

Crystalline_Clear Explanation. Thanks you Sir, for such a wonderful lectures.

[@andyalice6673]

Whenever watching Prof. Shenoy's lecture video, always could learn something or have more insightful understanding.

[@alib.2773]

You are fantastic!

[@naoremedisonsingh6035]

Simply the best. TOday is my solid state device exam and came for Schottky contact ; end up watching the entire video.

[@maal9996]

I love your teaching style and I love that you devoted your time for chalking on blackboard. Now I understand clearly about the Schottky and nearly Ohmic. Thank you so much.

[@praveen7028]

It didn't seem like an Hour lecture. Loved it!!!

[@108ahah]

awesome! you did what my lecturer can't in just 1 hour. Thank you!

[@cedtebann]

Well explained. Thanks so much! Regards from Salamanca, Spain.

[@shammisingh4701]

tunneling explanation was the beauty of the lecture, excellent lecture

[@gauravbassi5871]

i can see complete dedication of this sir to draw multiple diagram to teach the students

[@celebritylive7]

Amazing explanation,simple language nd proud to have like this teachers in our country(India) and intitutions.

[@alokkumarverma5271]

A very nice and simple explanation. It is very helpful for my solar cell technology research work

[@richadobal492]

Thank you much sir for this easy explanation.. regards from IIT Gandhinagar

[@mistrma11]

You are fantastic sir! I understood, finally!!

[@lumierenal9332]

Thank you sir, i learn more

[@garrytalaroc]

He is so good at teaching, I can easily understand.

[@sallyzhang7386]

I like this professor. He has lighter (almost none) accent!

[@adithyapai6158]

Good basics about Schottky and ohmic contact Thanks a lot iit.

[@muralidhar40]

Schottky starts at 21:30

[@MaheshGupta-vm3kq]

Tqs sir your teaching manner is very clear and very easy

[@nihuo3388]

Excellent explanation! thank you so much professor!

[@الاستاذ_فهد_الفعاس]

جزاك الله خير الجزاء

[@priyamsaha]

Sir, Apni BOSS....

[@ThuyPham-gf3ez]

it is a very useful lecture. Professor, could you please advise in the case of junction between Au and In2O3? What metal is best for In2O3 so that I could get a very near Ohmic contact? Thank you very much.

[@davicarvalho6193]

Very good lecture Greetings from Brazil

[@anamikasrivastava8714]

Very nice explanation thank you...sir 🙂

[@TufaanFORyou]

Very good lecture..clearing the doubts....

[@iamsatyamsaurav]

8 yrs....still the best

[@zihadazad]

[@asmatak]

Excellent Sir.

[@Health_asset]

Thanks sir for my concept building 🙏🏻🙏🏻👍🏻

[@marimuthu-xd2rj]

Excellent teaching

[@heavenintheworld195]

awesome lecture ......very easy to understand

[@raphaelkharkukhi1780]

49:50 when it is reversed biased, why is the fermi level of semiconductor and of metal not aligned? Please answer sir. Btw great lecture

[@abhiramdinavahi2071]

1. When you connect two different materials (metal and semiconductor in this case) without any external bias, charges flow from one material to another until the Fermi levels align. This corresponds to the “Equilibrium energy band diagram” 2. When you apply voltage across a device which has achieved equilibrium, you add energy to (or subtract energy from, depending on the polarity) every energy state in the bulk of one of the materials relative to the other material. Hence, for this reverse biased case which you asked about, every energy state (Ec, Ev, EF and Evacuum included) in the bulk of the semiconductor moves “downward” in energy relative to the metal. (Note however that the energy levels at the junction are pinned) Hence, the Fermi levels are not aligned any more. Long story short, Fermi levels align only under equilibrium (applies to semiconductor-semiconductor junctions also)

[@sreeram3594]

when there is no bias fermi levels on both sides are equal.when ever it is biased fermilevels on both sides become unequal.

[@erabudiprayekti4775]

Thank you for your explanation Prof

[@vkp3192]

Nice explanation. Thank you sir!

[@cici6605]

You are a great profesör thank you🙏

[@shakerbidier140]

Thank you Prof, very clear explanation

[@soniagulati9128]

Very illustrative....,.

[@sparshsharma7969]

amazing content

[@Kangleiluwangcha]

Sir i want to know how p-type semiconductor form Schottky junction?

[@bheemlal76]

Verey nice lecture and explanations

[@الاستاذ_فهد_الفعاس]

Where I can find all lectures? Please answer me

[@smartmind7665]

i like your explination thnk you sir good luck

[@bharat45672000]

Great detailed explaining.

[@ywk7282]

Is the case where the work function of metal is lower than the electron affinity of the semiconductor like a 2DEG where electrons are trapped in potential well?

[@chacho0001]

Any of you know where to find a detailed explanation for p-type and metal Schottky junction?

[@gyropitopia]

Fantastic lecture. Thank you

[@vaibhavpardhi3240]

Thank you very much sir. Great explanation...

[@nipukumardas9646]

Very good lecture, Thank you sir

[@shuvbhowmickbestin]

Why does the discountinuity arise only for schottkey diodes but not for ohmic contacts?

[@junwoobak]

Impressive lecture

[@nnnajwa]

thanks a lot! now i know why the diagram looks like that in my lecture note TT

[@live4Cha]

excellent!

[@emmanuelthibau5799]

wonderful teacher.

[@sandipkaran5741]

thanks sir,it is very helpful to carrier builder

[@rafiyamajeed1102]

can any one tell the name of the book please

[@roserose2862]

Very intresting.

[@KakoriaAshish]

can you please provide Answer figure for the quiz ?

[@NaziaKhatoon-k7u]

Thankyou sir ❤

[@joeljeevantharakan7349]

Thank you sir😄

[@suryanshsinghrawat961]

In the end of the lecture the question that he gave Al and InAs with 4.4eV and 4.9eV, How it doesn't have any schottky barrier ? Isn't it 0.5eV ?

[@yasirpunathil7143]

christoph waltz tone at 16:11

[@stefano.a]

Very clean explanation but: what are the conditions to form a Shottky barrier for a Shottky diode? Can someone please tell me the answer?

[@lekasree2548]

Work function of metal should greater than work function of semicondictor

[@MohammedIslamElshiekhElsmani]

Interesting!!

[@untold_cambridge]

Thank you professor

[@b_107_satyakisaha6]

7 years sir similar impact

[@Roghaiyeh]

very helpful, thanks a lot

[@sourcecreator2222]

excellent

[@soumallyabanerjee221]

Thank you very much sir.

[@varunjohnson9570]

left side first row students don't like they are below 20

[@jaeyoungkim4000]

wonderful.....

[@yihuaxie4248]

wonderful

[@manoj4558]

Why metal has high work function than semiconductor? As metal is conductive and according to phtoelectric effect it needs low energy to eject electron

[@Randsome1]

Ur dumb

[@ocayaro]

Brilliant

[@yananliu7885]

Thank you

[@dimplesingh6645]

thanku sir,

[@salwynmathew8545]

Can someone share the answer to the quiz?

[@suryasathya8626]

Thanks a lot

[@manasmishra4736]

Can u give notes on this

[@balu2005]

thank u sir

[@locoiamable]

Great Great Great!!!

[@cansuilhan380]

Can anyone share the answer to Quiz-5? (At the end of the video).
