An attempt is made to investigate the diamagnetic and paramagnetic susceptibilities of electrons in a quantum box of an n‐type wide‐gap semiconductor by considering perturbational effects of an external magnetic field. The results are computed for quantum cubes, taking n‐GaAs as an example. The susceptibilities are found to be oscillatory in nature because of the quantum size effect, while the ratio of the susceptibilities is observed to deviate significantly from the value well‐known for bulk semiconductors.

In this paper, we study the Einstein's photoemission from III-V, II-VI, IV-VI and HgTe/CdTe quantum well superlattices (QWSLs) with graded interfaces and quantum well effective mass superlattices in the presence of a quantizing magnetic field on the basis of newly formulated dispersion relations in the respective cases. Besides, the same has been studied from the afore-mentioned quantum dot superlattices and it appears that the photoemission oscillates with increasing carrier degeneracy and quantizing magnetic field in different manners. In addition, the photoemission oscillates with film thickness and increasing photon energy in quantum steps together with the fact that the solution of the Boltzmann transport equation will introduce new physical ideas and new experimental findings under different external conditions. The influence of band structure is apparent from all the figures and we have suggested three applications of the analyses of this paper in the fields of superlattices and microstructures. © 2009 Elsevier Ltd.

Superlattices and Microstructures

Simple theoretical analysis of the Einstein's photoemission from quantum confined superlattices

In this paper, we have investigated the threshold energy required for photoelectric emission of electrons from a torroidal quantum ring of degenerate narrow-gap semiconductor. Current density due to electrons emitted from the ring illuminated by normal radiation has been calculated considering the effect of band non-parabolicity of the narrow-gap semiconductor. The computed results show that the current density increases in a staircase manner with the increase of incident photon energy. The band non-parabolicity causes the increase in threshold energy for photoelectric emission of electrons. The photoemission becomes an oscillatory function of the cross-sectional radius of the ring, and may serve as an important tool for estimating parameters like cross-sectional radius, doping density and band non-parabolicity. © 2008 Elsevier B.V.
