TL;DR: In this article, the properties of Zn diffusion in the III-V ternary alloy semiconductor In1-xGaxP have been investigated, and the authors showed that the diffusion depth changed in proportion to the square root of diffusion time and decreased with composition.
Abstract: The properties of Zn diffusion in the III-V ternary alloy semiconductor In1-xGaxP have been investigated The Zn diffusion depth changed in proportion to the square root of diffusion time and decreased with composition of In1-xGaxP The effective diffusion constant at a given temperature was decreased with composition, while the activation energy for Zn diffusion was increased, due to a lower contribution of the interstitial diffusion with increasing Ga atom content in In1-xGaxP

TL;DR: In this article, the negative resistance and current oscillation in oriented polypropylene (OPP) were measured according to changes in temperature and field, and it was shown that negative resistance can be interpreted based on J.F. Gibbons' (1967) formulation.
Abstract: Oscillation phenomena accompanied by negative resistance were studied experimentally in oriented polypropylene (OPP). The negative resistance and current oscillation in OPP were measured according to changes in temperature and field. It is shown that the negative resistance can be interpreted based on J.F. Gibbons' (1967) formulation. The mobility can be calculated from the oscillation current. >
