Abstract
A new method for calculating the effects of size quantization upon the valence subbands in the zincblende semiconductors has been developed. A brief description of the method is presented, together with the calculated subband structure of a one dimensional quantum well wire. The subband structure is more complex than the case of the conduction band, possessing large nonparabolicities and effective masses different from the bulk. Our results show that the subbands can have a lower effective mass than the heavy hole mass. This may allow for the implementation of faster P-type devices and complementary circuits. Better computational methods for the subband structure of the valence subbands are useful for the design and modeling of lasers, light detectors, bipolar transistors, and any other devices which utilize holes in quantum wells.
