AbstractThe dependence of the static permittivity of single-crystal germanium on hydrostatic pressure up to P ≈ 7.4 GPa is studied experimentally. As the pressure is increased to P ≈ 4 GPa, the permittivity of Ge decreases by a factor of ~13 to ε = 1.22. As the pressure is increased further to P ≈ 7 GPa, a moderate increase in ε to the initial value is observed. In the range 7–7.4 GPa, the permittivity increases to a value larger than 1000. The experimental dependences obtained in the study substantially differ from the previously known dependences.

Effect Of Hydrostatic Pressure

AbstractThe effect of hydrostatic pressure up to P = 1.7 GPa on the fluctuation conductivity σ′(T) and pseudogap ∆*(T) in Y0.95Pr0.05Ba2Cu3O7−δ single crystal with critical temperature Тс = 85.2 K (at P = 0) was investigated. The application of pressure leads to the increase in Tc with dTc/dP = +1.82 K∙GPa−1 while the resistance decreases as dlnρ(100 K)/dP = −(10.5 ± 0.2) %∙GPa−1. Regardless of the pressure, in the temperature interval from Tc to T0 (~88 K at P = 0) the behaviour of σ′(T) is well described by the Aslamazov – Larkin (AL – 3D) fluctuation theory, and above the T0 by the Lawrence – Doniach theory (LD). The Maki-Thompson (MT – 2D) fluctuation contribution is not observed. This indicates the presence of structural defects in the sample induced by Pr. Here it is determined for the first time that when the pressure is applied to the Y1−xPrxBa2Cu3O7−δ single crystal, the pseudogap increases as dlnΔ*/dP = 0.17 GPa–1.
