The electronic carry coefficients, transmittance and the currentvoltage uniqueness were measured the length of the three principle axis via the Wannier WanT Distribution put together. Plane-wave pseudo potential (DFT), as incorporated in the (PWSCF) set of laws of the Quantum Espresso distribution have been utilized to evaluate the electronic properties of abundant stress-free Ge structure. The generalized gradient approximation Perdew Burke-Ernezerhof (PBE) pseudopotential. Another, by using different equation of state to evaluate the variation of lattice constant with pressure, and then evaluate the variation of (Eg) with pressure.

High pressure physics is a challenging branch of physics, in which one has to produce, apply and measure high pressure on the material and study the physical properties at a given pressure simultaneously. This means that these pressures need to be sustained for times long enough. The pressure dependence of (magnetization per unit mass) of iron and nickel under hydrostatic pressure up to 0.25 k bar and found that the variation is too small to be determined quantitatively. But the author found that ∂σ/∂p was negative for iron and positive for nickel. A subsequent repeat of these measurements by the same workers gave negative values for this pressure effect in nickel also.
