Exploring Fundamental Mechanisms of Near-Field Energy Conversion

Abstract

Major Goals: This proposal seeks to leverage novel thin-film based homo- and hetero-structured devices to elucidate a number of fundamentally new radiative heat transfer and energy conversion processes that arise in the near-field. In fact, near-field radiative heat transfer (NFRHT), which occurs in a regime where the gap-size between hot and cold objects is less than the Wiens wavelength, is an area of great current interest due to both its fundamental importance and technological potential. While far-field radiative transport is well understood, there remains a significant gap in current understanding of NFRHT. During the last decade, computational studies have predicted a number of novel transport and energy conversion phenomena which include potentially transformative approaches for: a) thermophotovoltaic energy conversion by leveraging near-field effects in conjunction with low band-gap materials and b) electro-luminescent based refrigeration using thin-film heterostructure devices.
