A Semiconductor is known to have electron effective mass of 0.34mo, where mo refers to free electron mass. It is found that the average time between the momentum randomizing collisions in this semiconductor is 44.4 ps. What is the mobility of the electrons in this material? Please calculate your answer within two decimal places and also indicate units.

The mass density of silver at room temperature is 10.5 x 103 kg/m3 and its atomic mass is 108g/mol. If we assume there is one free electron per silver atom, what is the free-electron desity for silver, in electrons/m3? How does this compare to the free electron density of Copper?
