Video Solutions for GATE 2007 ECE : One Mark Questions (Electron Devices)

1. The electron and hole concentrations in an intrinsic  

    semiconductor are n_i per cm³ at 300^oK. Now, if acceptor  

    impurities are introduced with a concentration of N_A per cm³ 

    (where N_A  > n_i ), then electron concentration per cm³ 

     at 300^oK will be 

2.  In a P⁺N junction diode under reverse bias, the magnitude of 

     electric field is maximum at

3. The correct full wave rectifier circuit is :
