Electronic g‐factor in Cd₃As₂

Abstract

Using the Bodnar model, the effective mass, density of states, and g-factor of Cd,As, are calculated.It is found that the g-factor is considerably more anisotropic than the effective mass, but decreases sharply with energy in all directions.Kous avons calculk, A partir du modde de Bodnar, la masse effective, le densiti? d'6tats e t le facteur g de Cd,As,. Nous trouvons que le facteur g est beaucoup plus anisotrope que la masse effective, e t diminiie rapidement en fonction de l'knergie pour toutes les directions cristallographiques.

Effect of varying the orientation of a quantizing magnetic field on the effective electron mass in degenerate tetragonal semiconductors

“…This is done in what follows by taking n-Cd3As, as an example which is usually grown as degenerate n-type crystals having non-standard energy bands and which also has been relatively much less investigated for its different physical aspects [6 to 161. Incidentally, i t may be noted that, in spite of the tetragonal crystal structure of Cd,As, and the early observation of the conduction band anisotropy by Rosenman [7] [7,10,13] in Cd,As2 have provided strong evidence for the validity of the Bodnar model according to which the conduction band in tetragonal semiconductors has ellipsoidal shape in k-space with the anisotropy dependent on energy. I n fact, the Bodnar model is based on the 12 -p treatment with the assumption of a n inverted band structure and isotropic spin-orbit splitting.…”

Effect of Magnetic Quantization on the Diffusivity—Mobility Ratio in n‐Cd3As2

“…Using this dispersion relation, Wallace [12] has shown that the energies of the quantized levels under magnetic quantization (taking spin into account) are determined from the equation…”

The Effect of Anisotropy on Resonant Tunnelling Spin Polarization in Type-II Heterostructures

“…The commutation relations for the wave vector components in the primed coordinate system are given by ½k x ; k 0 y ¼ Ài=l 2 , in which l is the usual cyclotron radius measured in natural units [20]. Taking into account these commutation relations, the 8 Â 8 k Á p matrix Hamiltonian reduces to a 2 Â 2 pseudo-matrix Hamiltonian [21][22][23]:…”
