Title: metal semiconductor contact Post by rajesh14 on Oct 16th, 2009, 10:18am hi all.. i want to know whats happening when metal n semiconductor come into contact ... can anyone explain exactly whats going on there...i didnot get why the energy band diagrams bend at contact under thermal equilibrium...? |
Title: Re: metal semiconductor contact Post by raja.cedt on Oct 18th, 2009, 9:35pm hi, actually in thermal equilibrium current should be zero..so Fermi level should be flat. so keep your fermi level flat and complete remaining Energy Band diagram. otherwise you can say like you need electric field to stop carrier exchange at thermal equilibrium. You can get this info in street man book Thanks, rajasekhar |
