Radiation heat transfer is critical for solar energy utilization, building thermal management, and high-temperature thermal systems. Recent advancement in micro/nanofabrication techniques has enabled the fabrication of novel structures with engineered radiative properties. Ability to tailor radiative properties is a direct result of the interaction between electromagnetic waves and surface nano/micro structures in the near-field regime (i.e., at the length scale comparable to the characteristic wavelength). It has been shown that near-field effects can lead to the realization of new technologies including subwavelength heating sources, polariton-assisted nanomanufacturing, and biomedical sensors. Particularly, near-field thermal radiation has been intensively investigated for potential applications such as a highly sensitive thermal microscopy and a near-field thermophotovoltaic energy conversion system. To facilitate these applications, it is crucial to fundamentally understand the radiative transfer at the nanometer scale.

Ultimate Goal of TRAD Lab is to make a significant impact on future applications of nanoscale thermal radiation for energy conversion and utilization.

We conduct fundamental research on the light-matter interaction at nanometer scales, especially for photon tunneling and electric/magnetic resonance phenomena, and employ nanotechnology to control thermal radiative transfer per our needs.

The Research Topics of TRAD Lab includes:

    • Near-Field Thermophotovoltaic Energy Conversion System
    • Solar Energy Harvesting System using Nanomaterials
    • Micro/Nanoscale Thermometry
