Chiral molecules based nano spitronics devices
With the increasing demand for miniaturization, nano-structures are likely to become the primary components of future integrated circuits. Different approaches are being pursued towards achieving efficient electronics, among which are spin electronics devices (spintronics). In principle, the application of spintronics should result in reducing the power consumption of electronic devices. A new, promising, effective approach for spintronics has emerged using spin selectivity in electron transport through chiral molecules, termed Chiral-Induced Spin Selectivity (CISS). Studying the CISS effect it was found that chiral molecules, and especially helical ones, can serve as very efficient spin filter. Recently, by utilizing this effect we demonstrated a magnet less spin based magnetic memory. The presented technology has the potential to overcome the limitations of other magnetic-based memory technologies to allow fabricating inexpensive, high-density universal and embedded memory-on-chip devices. Another option is to achieve local spin-based magnetization generated optically at ambient temperatures, as well as local charge separation using light induced configuration.
