摘要：

In analogy to the central role of transistors in conventional electronics, a key device in spintronics, spin field effect transistor (spin FET), has been predicted theoretically. Several approaches have been explored, but their applications remain a considerable challenge due to the small spin signals and low working temperature. In this work, we report a four-terminal spin FET using an individual SWNT with two partially open segments and the working mechanisms is closely related to the magnetic moments at these segments. The spin-related signals (Rspin) can be as large as several hundred Ohm and the spin FET works at room temperature under atmospheric conditions. Rspin can be modulated with gate voltages and external magnetic fields. The realization of spin FET may lead to the development of integrated circuit of spintronics, which is fundamentally different from charge-based conventional electronics. (c) 2021 Elsevier B.V.
