We derive the many-body theory of the effective mass in the effective mass representation (EMR). In the EMR, we need to solve the equation of motion of an electron in the presence of electron–electron interactions, where the wavefunction is expande

We derive an expression for the effective mass of an electron for a multi-band system, starting from a thermodynamic potential expressed in terms of a single-particle Green's function and using an effective equation of motion in the effective mass re

Ternary alloys on the quasi-binary system Ni3Sn(r) in equilibrium condition. It has been observed that these phases undergo transformations at high temperatures but upto 500 °C room temperature modifications are stable. The two phases do not have an

The Debye–Scherrer pattern of the alloy Ni80Zr20 clearly shows the presence of a nickel solid-solution phase along with a new intermetallic phase Ni23Zr6, which seems to be isostructural with the Co23Zr6 phase. The thermal expansion coefficient of

The lattice spacings of the intermetallic compound Ni3Zr have been measured by X-ray methods in the temperature interval 298–1033 K using a Debye–Scherrer camera. In all the cases the measured lattice spacings have been found to increase non-line
