1. why voltage drop low at metal-semiconductor junction?
ans:
When sufficient voltage is applied to schottky diode, current starts flowing in the forward direction and a small voltage loss occurs across the terminal of schottky diode.
2. Is the type of semiconductor effect the voltage drop?
ans : 
yes, it is effected because each semiconductor have majority and minority carriers. For example, pn junction carriers are different with metal n-type semiconductor. That is why it is effect the voltage drop.

1. What will happen when forward voltage exceeds the internal barrier voltage?
When the forward voltage exceeds the diodes P-N junctions internal barrier voltage, which for silicon is about 0.7 volts, avalanche occurs and the forward current increases rapidly for a very small increase in voltage producing a non-linear curve. The “knee” point on the forward curve.

2. Does Semiconductor diodes are characterized by linear current–voltage characteristics?
No,semiconductor diodes are characterized by non-linear current–voltage characteristics as the current flowing through a forward-biased common silicon diode is limited by the ohmic resistance of the PN-junction.]]> 2017-04-30 04:37:41 UTC https://padlet.com/namymyj05r/3id3t18rasph/wish/169039076 Questions and Answers for Metal Semiconductor Junction Topic https://padlet.com/namymyj05r/3id3t18rasph/wish/169043216 Group Members:

1) What happen if there is no minority carrier injection occurs in forward bias of Schottky Diode?The Schottky diode is a majority carrier device. Unlike a p-n diode, in forward bias no minority carrier injection occurs. Thus there is no diffusion capacitance and the device response can be very fast.

2)What is the mean by the term of Ohmic Contact in Metal Semiconductor junction?
By using easy terms Ohmic Contact is no potential exists between metal and semiconductor .A metal-semiconductor junction results in an Ohmic contact ) if the Schottky barrier height, fB, is zero or negative. In such case, the carriers are free to flow in or out of the semiconductor so that there is a minimal resistance across the contact.
