Problem 3. – 10 Points total – (a) = (b) = 5 pts THIS CONTENT IS PROTECTED AND MAY NOT BE SHARED, UPLOADED, SOLD, OR DISTRIBUTED The concept of effective mass that is discussed in Chapters 3.2 and 3.3 can be understood as the curvature of the E-k diagram at the bottom of the band near its minimum. However, ultra-scaled modern semiconductor devices may operate under high electric field conditions resulting in the carriers not being near the minimum of the E-k band diagram. In this case, the effective mass is not a constant but a function of the wavenumber k. For example, the conduction energy band of a given semiconductor around the
