초록

반도체 스핀트로닉스는 자성체와 반도체를 결합하여 반도체 내에서의 전자 스핀을 이용하는 새로운 형태의 자성체-반도체 융합기술이며, 스핀 트랜지스터는 반도체 스핀트로닉스의 대표적인 소자이다. 이 소자를 실현하면, 반도체 내에 전자 스핀을 주입, 제어, 검출함으로써, 한 소자 내에서 정보처리와 정보저장을 동시에 수행할 수 있을 것으로 기대된다. 특히, 반도체 산업의 주축 물질인 실리콘을 이용하여 스핀 트랜지스터를 실현한다면, 이는 정보 산업에 중대한 영향을 미칠 것으로 예상된다. 이 글에서는 최근 실리콘 스핀트로닉스 분야에서의 주요한 진전을 소개하고, 앞으로의 기술적 과제에 대하여 간단히 기술하고자 한다.

Semiconductor spintronics is an emerging interdisciplinary technology based on the electron spin degree of freedom, combining the magnetic materials and semiconductors. The spin transistor represents a novel semiconductor device, in which the electron spin is injected, manipulated, and detected, and thereby a memory function and data processing function are enabled in one device. Particularly, the spin transistor based on Silicon, the mainstream semiconductor, might have a significant impact on information technology. This review introduces the major progresses of Silicon spintronics in recent years, and describes the technical issues for the future.
