Determination of the specular reflection coefficient of conduction electrons in Zn whiskers atT=4.2°K

Determination of the specular reflection coefficient of conduction electrons in Zn whiskers... The influence was studied of the transverse dimensions of Zn single crystals in the form of whiskers and thin platelets on their specific resistance atT=4.2°K. The thickness of the specimens measured ranged from 10 µm to 0.2 µm. With a decreasing thickness of the specimens the specific resistance increased considerably.

Abstract

The influence was studied of the transverse dimensions of Zn single crystals in the form of whiskers and thin platelets on their specific resistance atT=4.2°K. The thickness of the specimens measured ranged from 10 µm to 0.2 µm. With a decreasing thickness of the specimens the specific resistance increased considerably. Under the assumption that for a pure diffuse reflection of electrons on the specimen boundary the product (ρ∞ ·d ∞) in a bulk specimen is equal to 1.8×10−11 Ωcm2 for a crystallographic orientation corresponding to whiskers, and 2.2×10−11 Ωcm2 for a crystallographic orientation corresponding to platelets, a specular reflection coefficientp approximately equal top=0.6 was calculated for both whiskers and platelets.
