Samsung pushes graphene one step closer to silicon-supremacy
Graphene has long-held notions of grandeur over its current
silicon overlord, but a few practical issues have always kept
its takeover bid grounded. Samsung, however, thinks it's cracked
at least one of those -- graphene's inability to switch off
current. Previous attempts to use graphene as a transistor have
involved converting it to a semi-conductor, but this also
reduces its electron mobility, negating much of the benefit.
Samsung's Advanced Institute of Technology has created a
graphene-silicon "Schottky barrier" that brings graphene this
much-needed current-killing ability, without losing its
electron-shuffling potential. The research also explored
potential logic device applications based on the same
technology. So, does this mean we'll finally get our flea-sized
super computer implant? Maybe, not just yet, but the wheels have
certainly been oiled.  Show full PR text  Samsung Electronics
