| 摘要 |
A device includes a Schottky barrier formed by a metal-semiconductor junction between a semiconductor nanowire and a metal contact. The metal contact at least partly encloses a circumferential area of each nanowire along the length thereof. The nanowire includes a low doped region that is part of the metal-semiconductor junction. The device can be fabricated using a method where two different growth modes are used, the first step including axial growth from a substrate giving a suitable template for formation of the metal-semiconductor junction, and the second step including radial growth enabling control of the doping levels in the low doped region. |
