Abstract : The effect of the considerable depth of donor impurity states near the indirect <100> conduction band minima on the direct-indirect transition in Ga(AsP) is discussed. A simple technique for using a Ga(AsP) laser to operate a CdSe or Cd(SeS) laser is described. Ultra-thin CdSe lasers of variable mode spacing, including the special case of single-mode operation, are described. Current oscillations in Au-compensated Si p-'i'-n diodes were studied. These oscillations are essentially independent of the external circuit (i.e., they are not negative resistance oscillations) and are not attributable to transit time effects. The various parameters affecting these oscillations were examined, and a space-charge instability model which is in accord with the experimental data is proposed. (Author)
