Theory of effective g factors and effective masses in diluted magnetic semiconductors

RL Hota, GS Tripathi, JN Mohanty - Physical Review B, 1993 - APS
We derive an expression for the effective g factor in the presence of magnetic impurities. The
expression is suitably modified as to make it applicable to diluted magnetic semiconductors …

Electronic structure of high density carrier states in PbS, PbSe and PbTe

RK Das, S Sahoo, GS Tripathi - Semiconductor science and …, 2004 - iopscience.iop.org
Carrier concentration dependent electronic structures are usually studied through the
method. In the traditional method the band edge hamiltonians are diagonalized exactly and …

We derive a theory for the spin-contribution to the electron-paramagnetic resonance shift (P
s) for an electronic system in the presence of a periodic potential, spin-orbit (SO) interaction …

NMR chemical shift in PbTe and spin-orbit effects

RL Hota, RC Patnaik, GS Tripathi, PK Misra - Physical Review B, 1995 - APS
The observed large NMR chemical shift of Pb 207 in PbTe is explained, within the
framework of ak⋅ π method, mainly through a contribution attributed to the spin-orbit …

Indirect nuclear spin-spin interactions in PbTe

RC Patnaik, RL Hota, GS Tripathi - Physical Review B, 1998 - APS
We make a careful analysis of various contributions to the indirect 207 Pb nuclear spin-spin
interactions A jj′ in PbTe. The calculation takes into account all three hyperfine interactions …
