The depletion layer capacitance of n-type gallium arsenide was measured as a function of its anodic potential in an electrochemical cell. It was shown that these measurements can lead to accurate values of carrier concentration, and are compatible wi

The difficulties in obtaining well defined electrically active layers by ion implantation in gallium arsenide, and other bindary compound semiconductors, as compared with silicon, are discussed. An examination from first principles, in terms of the c

GaAs/AlxGa1−xAs double‐heterostructure layers grown by conventional LPE have been examined by three separate electrical and optical techniques. Some material has exhibited characteristics not previously detected in epilayers grown singly. Our cen

Changes in electrical conductivity of CdS films, deposited under ultra high vacuum and subsequently exposed to hydrogen adsorption, have been measured. From a plot of the rate of conductivity increase against reciprocal absolute temperature, an activ
