A theoretical investigation is made of the plasma-wave instability mechanism in a two-dimensional (2D) electron fluid in a field-effect transistor (FET) in the presence of a perpendicular magnetic field. The influence of electron collisions with impu

The rich diversity and the fundamental character of the essential theoretical problems associated with it have given band theory a width of interest which contrasts strongly with the apparent narrowness of its subject matter. This review, dealing mai
