硅自旋场效应晶体管的实验实现

Experimental realization of a silicon spin field-effect transistor

Biqin Huang, Douwe J. Monsma, Ian Appelbaum

摘要:

纵向电场用于控制自旋极化电子在垂直磁场中进动的渡越时间(通过未掺杂的硅垂直沟道)。由于所施加的电压确定自旋检测器处的最终自旋方向,因此确定输出集电极电流,因此这包括自旋场效应晶体管。改进的热电子自旋注入器提供~115%的磁电流,对应于至少~38%的电子电流自旋极化后,通过10微米的未掺杂的单晶硅传输,用于最大电流调制。

英文摘要:

A longitudinal electric field is used to control the transit time (through an undoped silicon vertical channel) of spin-polarized electrons precessing in a perpendicular magnetic field. Since an applied voltage determines the final spin direction at the spin detector and hence the output collector current, this comprises a spin field-effect transistor. An improved hot-electron spin injector providing ~115% magnetocurrent, corresponding to at least ~38% electron current spin polarization after transport through 10 microns undoped single-crystal silicon, is used for maximum current modulation.
