We have succesfully obtain a two dimensional atomic array by a state of the art nanofabrication technique. the energy bandgap of this material is found to be 2ev and its fermi level is located 0.2ev below he conduction band minium. utilizing the mathmethical relations given below, find the concentration of electros which can contribute to the current conduction. assume that the fd distributioncan be approximated to mb distribution

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r
