ABSTRACT
As complementary metal-oxide-semiconductor (CMOS) transistors near atomic-scale limitations, researchers are searching for novel devices to complement or supplant conventional silicon electronics. Several alternative devices have been proposed as potential successors to conventional Si CMOS. Unlike the transition from bipolar devices to CMOS, however, a clear successor to the metal-oxide-semiconductor field-effect transistor (MOSFET) has not yet emerged. Some devices offer improved speed, some promise unmatched power efficiency, and still others offer versatility and robustness through runtime configurability. Because no device is superior in every metric, future computing systems may offer heterogeneous integration of CMOS and other technologies, providing a judicious balance among the devices optimized for the particular performance metric desired.
