Paper Abstract

As semiconductor technology continues to drive the scaling of electronic device dimensions into the ultrasubmicron, nanodimensional regime, many ultrasmall and ultrafast concepts and phenomena will continue to be put-forth for notional consideration. The stunning achievements of nanofabrication technology in the last decade now allow for band-engineering and atomiclevel structural tailoring not heretofore available or explorable except through naturally occurring atomic and molecular processes. Appropriately, this paper addresses several novel concepts, some new and some revisited, for consideration as interesting future directions. Five main themes will be put-forth and discussed as "food-for-thought" in considering novel directions in nanophysics, namely: coherent, electric-field assisted interference of closely spaced quantum states to provide long-lived energy trapping and novel optical properties; many-body effects relevant to single-electron transfer in Coulomb blockade phenomenology; coherent, defect-assisted tunneling as a related component of excess current during the Zener tunneling process; stimulated, resonant transfer of localized electrons in a periodic potential due to time varying electric fields; and confined-phonons in nanoscale systems.
