expression for surface recombination velocity
vamshi posted a topic in Microelectronicscan any one help me in giving the derivation of surface recombination velocity in a semiconductor s=sqrt(Dp/tp)
vamshi replied to darya83's topic in Electronics chit chati worked with labview version 7 by national instruments but i know only a few basic operations in it tell me u r area of work i may help u if i can
it was my intrvw question in iitdelhi

voltage across 2 terminals of diode,transistor
vamshi posted a topic in Microelectronicswhen we measure the voltage across 2 terminals of a diode using a multimeter what does it show ? similarly with any 2 terminals of transistors what does these indicate??
doubt on mosfet symbols
vamshi posted a topic in Microelectronicsthe arrow mark in the symbol of a transistor/jfet indicates the conventional direction of hole current but why does mosfet have symbols opposite i.e.,in symbols for npn transistor and n channel fet why arrow diections are different
