摘要：
We study theoretically the photoemission from quantum wells (QWs), quantum well wires (QWWs) and quantum dots (QDs) on the basis of a newly formulated electron dispersion law considering the anisotropies of the effective electron masses, the spin-orbit splitting constants and the presence of the crystal field splitting within the framework of kp formalism. It has been found taking quantum confined CdGeAs2 and Hg1-xCdxTe as examples that the photoemission exhibits quantized variations with incident photon energy. The photoemission is the greatest for QDs and the least for QWs. The simplified results for wide gap nondegenerate materials can be obtained as a special case of our generalized analysis which is a compatibility test of our paper.
