Transistor? amplify?

  1. Aug 3, 2004 #1
    trying to figure out the meaning of lattice struction in semiconductor... :yuck:
    and, why a small current in the base circuit of a transistor can control a large current in collector part when "bipolar junction transmission" happened???
    Thanks for any help! :confused:
