The gunn effect and conduction band structure in Ga_xIn_1-xSb alloys

The observation of the Gunn effect in GaxIn1-xSb alloys is reported and shown to be consistent with a conduction band structure having a next higher set of minima along the <111> directions in k space above the lowest conduction band minimum at the center of the Brillouin zone for all values of x. © 1969.
