Abstract:
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). Recently, by
utilizing this effect we demonstrated a
magnet less spin based magnetic
memory [1]. The presented technology has
the potential to overcome the limitations
of other magnetic-based memory
technologies to allow fabricating
inexpensive, high-density universal
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 a slightly
different configuration [2].
