Research output: Contribution to journalConference articlepeer-review


We experimentally realize broad spectrum directional thermal emitters by developing subwavelength photonic film consisting of multiple oxides, as well as graded doped III-V semiconductors, that exhibit epsilon-near-zero (ENZ) regions at long-wave infrared wavelengths.
