Direct Observation of Tunnelling through 100-nm-Wide All Metal Magnetic Junction into Si

引用

Chinese Physics Letters 2008年第4期25卷 1407-1410页

作者： Nam h.kim 王克强张宇王建青 Department of Physics State University of New York Binghamton NY 13902 USA School of Information Zhongkai University of Agriculture and Technology Guangzhou 510225 Department of EleetrieaJ Engineering State University of New York Binghamton NY 13902 USA

Nanoscaled spin-dependent tunnelling lines were patterned on doped Si and studied for tunnelling from the SDT ferromagnetic layer through an insulating barrier into Si. The injection contacts have the form of long strips with width and separation, ranging from 100 nm to 2 μm, and are patterned using e-beam lithography. The measured I-V characteristics versus temperature （80 to 300K） on the 100 nm scaled devices between the layered-magnetic metals and the semiconductor clearly showed ballistic tunnelling, with weak dependence on the temperature. This is qualitatively different, at elevated temperatures, from 2-μm-wide scaled-up spin-dependent tunnelling structures, where thermal-ionic emission was observed to dominate carrier transport.
