Proposal of a topological insulator based magnetoelectric transistor
2014
A new type of transistor is proposed based on wave-guiding phenomena of topological insulator (TI) surface electrons for applications in CMOS-like circuits and switchable interactions in spin logic circuits. The carrier channel is patterned by the magnetic strip and the ON/OFF switch is achieved by the electrically controlled magnetic valve (Fig. 1A). We characterized the current-gate voltage (I d -V g ) relation and the time resolved performance. Very low subthreshold swing (below 10 mV/dec) and operating frequency above 1 GHz are expected.
