Title: Heat meets light on the nanoscale

Abstract

Abstract We discuss the state-of-the-art and remaining challenges in the fundamental understanding and technology development for controlling light-matter interactions in nanophotonic environments in and away from thermal equilibrium. The topics covered range from the basics of the thermodynamics of light emission and absorption to applications in solar thermal energy generation, thermophotovoltaics, optical refrigeration, personalized cooling technologies, development of coherent incandescent light sources, and spinoptics.

  • We discuss the state-of-the-art and remaining challenges in the fundamental understanding and technology development for controlling light-matter interactions in nanophotonic environments in and away from thermal equilibrium. Furthermore, the topics covered range from the basics of the thermodynamics of light emission and absorption to applications in solar thermal energy generation, thermophotovoltaics, optical refrigeration, personalized cooling technologies, development of coherent incandescent light sources, and spinoptics.
  • This article examines the natural gas engine driven heat pump popular in Japan. The topics of the article include the history of the gas heat pumps, how they work, the track record of the gas heat pump in Japan, the results of US field tests, the market for gas heat pumps in the US. The unit is promoted to offer to homeowners the possibility of choosing a cheaper fuel for cooling; to state regulators, a chance to encourage the use of a technology that benefits gas and electric ratepayers, increases efficiency, and fosters environmental quality; to gas utilities, an opportunitymore » to reduce the seasonably of customer gas loads; and to electric utilities, possibly a new demand-side management tool that lowers peak loads and defers new power plant construction.« less
  • The external quantum efficiency of white organic light-emitting diodes is often limited by light out-coupling losses due to surface plasmons. We demonstrate how texturing of the metal-cathode surface using a two-dimensionally periodic lattice of nanoscale scatterers with limited disorder can be used to reduce plasmonic losses while simultaneously enhancing both the light out-coupling and the spontaneous-emission rate of the excitons. We use electrodynamic simulations and statistical modeling to explore the relationship between the topology of the surface texture and its corresponding scattering efficiency. From this, we outline attributes of textures that can most enhance device performance.
  • Molecule-scale structure effects at indium tin oxide (ITO) anode-hole transport layer (HTL) interfaces in organic light-emitting diode (OLED) heterostructures are systematically probed via a self-assembly approach. A series of ITO anode-linked silyltriarylamine precursors differing in aryl group and linker density are synthesized for this purpose and used to probe the relationship between nanoscale interfacial chemical structure and charge-injection/electroluminescence properties. These precursors form conformal and largely pinhole-free self-assembled monolayers (SAMs) on the ITO anode surface with angstrom-level thickness control. Deposition of a HTL on top of the SAMs places the probe molecules precisely at the anode-HTL interface. OLEDs containing ITO/SAM/HTL configurationsmore » have dramatically varied hole-injection magnitudes and OLED responses. These can be correlated with the probe molecular structures and electrochemically derived heterogeneous electron-transfer rates for such triarylamine fragments. The large observed interfacial molecular structure effects offer an approach to tuning OLED hole-injection flux over 1-2 orders of magnitude, resulting in up to 3-fold variations in OLED brightness at identical bias and up to a 2 V driving voltage reduction at identical brightness. Very bright and efficient ({approx}70 000 cd/m{sup 2}, {approx}2.5% forward external quantum efficiency, {approx}11 lm/W power efficiency) Alq (tris(8-hydroxyquinolinato)aluminum(III))-based OLEDs can thereby be fabricated.« less
  • An experimental technique for measuring time-resolved coherence loss and destruction of backscattered wavepackets in random media is described. The results of such measurements, performed with a modified Michelson interferometer, contain rich information about the characteristics of media nonuniformities. Experimental data for model nanosuspensions are compared with theoretical expressions developed in the article which include the effects of Mie-type resonant scattering. One such observed effect is attributed to enhanced inelastic optical transitions near the surface of nonmetallic nanoparticles. The inverse problem of characterization of multiscattering random media by backscattering is considered.
