I have a query regarding a question given in ADC test: Question was: A sample of Ge is doped to an extent of 10¹⁴ donor atom/cm³ and 5x 10¹³ acceptor atom/cm³ at 300k the intrinsic Ge is having the resistance of 60 ohm-cm . find the conduction current if an electric field of 2V/cm is applied. In notes we solve the same question using the formula n=Nd/2+√Nd²/4+ni² but in the solution given for the test has taken n=Nd and p=Na Please tell the correct solution.
IES 2019 will be conducted in the month of January 2019. Candidates are called in to apply for the examination from 26th September 2018 (tentative). Union Public Services Commission will be organizing the examination for the IES 2019. The tentative dates are shared here. It is advised though the candidates must keep a track on the regular updates for any changes in the dates of the examination.
