Abstract
Current information technologies use semiconductor devices and magnetic/opt ical discs, however, it is foreseen that they will all face fundamental lim itations within a decade. This paper reviews the prospects and problems of single molecule devices, including switching devices, wires, nanotubes, opt ical devices, storage devices and sensing devices for future information te chnologies and other advanced applications in the next paradigm. The operat ion principles of these devices are based on the phenomena occurring within a single molecule, such as single electron transfer, direct electron-hole recombination, magnetic/charge storage and regand-receptor reaction. Four p ossible milestones for realizing the Peta (10(15))-floating operations per second (P-FLOPS) personal molecular supercomputer are described, and the ne cessary technologies are listed. These include, (1) two terminal conductanc e measurement on single molecule, (2) demonstration of two terminal molecul ar device characteristics, (3) verification of three terminal molecular dev ice characteristics and (4) integration of the functions of "molecular supe r chip". Thus, 1000 times higher performance information technologies would be realized with molecular devices.
