Question

Germanium to which 5 Times 1022 m-3 Sb atoms have been added is an extrinsic semiconductor at room temperature, and virtually all the Sb atoms may be thought of as being ionized (i.e., one charge carrier exists for each Sb atom), (a) Is this material n-type or p-type? (b) Calculate the electrical conductivity of this material, assuming electron and hole mobilities of 0.1 and 0.05 m2/V-s, respectively. Given Electron charge - 1.602 Times 10-19 Coulombs The figure below represents the I-V curve of a p-n junction. Using this figure explain operation of the p-n junction both in forward bias and reverse bias modes

Explanation / Answer

In forward direction it will not conduct till it cross the 0.5v bearer after hat it start conductiong in forward direction while in reverse it will not conduct till the reverse break down occurs.

A). it is P-type in start after 0.5v i urns inn-type.
