Carbon nanotubes (NTs) have been studied by material scientists since 19521, but became a worldwide research focus only after fullerenes were discovered and after single-walled carbon nanotubes (SWNTs) were introduced to the research community in 19932. The simplicity of their synthesis and the diversity of their properties3 quickly propelled NTs into electronics, optics, nanoand biotechnology ...
We show that periodically folded graphene sheets with enhanced spin-orbit interaction due to curvature effects can carry spin-polarized currents and have gaps in the electronic spectrum in the presence of weak magnetic fields. Our results indicate that such origami-like structures can be used efficiently in spintronic applications. Copyright c © EPLA, 2013 Often hailed as a wonder material due ...
Introduction. It is a great honor to contribute to Gabriele Giuliani memorial volume, and it has been remarkable experience to work with Gabriele. In the past 15 years Condensed Matter physicists became greatly interested in spindependent phenomena, creating a direction of spintronics research [1]. Gabriele was genuinely interested in this trend, involved his students in research in this field,...
Current interest in spintronics is largely motivated by a belief that spin based devices (e.g. spin field effect transistors) will be faster and consume less power than their electronic counterparts. Here we show that this is generally untrue. Unless materials with extremely strong spin orbit interaction can be developed, the spintronic devices will not measure up to their electronic cousins. W...
Spintronics attracts at present much interest because of the potential to build novel spin-based devices which are superior to charge-based microelectronic elements. Silicon, the main element of microelectronics, is promising for spin-driven applications. Understanding the peculiarities of the subband structure and details of spin propagation in thin silicon films in the presence of the spinorb...
