Electrically conductive rod-shaped single crystal product and assembly for measuring electrical properties employing such product, as well as processes for their production

摘要

An electrically conductive rod-shaped single crystal product, which is a rod-shaped single crystal having an aspect ratio of from 1 to 500, formed by a vapor-liquid-solid method or such a rod-shaped single crystal having its forward end alloy portion removed, wherein at least side surface of said rod-shaped single crystal is coated by an electrically conductive film having a thickness of from 0.1 to 10 &mgr;m.
