Abstract:Summary form only given.
The spin-valve transistor (SVT) is a three terminal device in which hot electrons are emitted over a Schottky barrier, they cross a metallic spin valve and are collected with energyand momentum selection. While SVTs with high relative magnetic response (above 300% at room temperature) have been made, the absolute value of the output (collector) current (1c) is still low (I/sub C/ = 10nA at I/sub E/ = 2mA). Although this is sufficient to study spin-dependent hot-electron transport across magnetic layers, it is certainly a disadvantage for practical applications. We will present three routes to increase the collector current by enhancing the transfer ratio.
