Exciton Binding Energy of Monolayer WS2 [PDF]

, 2014
The optical properties of monolayer transition metal dichalcogenides (TMDC) feature prominent excitonic natures. Here we report an experimental approach toward measuring the exciton binding energy of monolayer WS2 with linear differential transmission ...

The Exoplanet Transmission Spectroscopy Imager (ETSI) [PDF]

Ground-based and Airborne Instrumentation for Astronomy VIII, 2020
We present the design of a novel instrument tuned to detect transiting exoplanet atmospheres. The instrument, which we call the exoplanet transmission spectroscopy imager (ETSI), makes use of a new technique called common-path multi-band imaging (CMI).

A new powerful method for probing the atmospheres of transiting exoplanets

, 2004
Although atmospheric transmission spectroscopy of HD209458b with the Hubble Space Telescope has been very successful, attempts to detect its atmospheric absorption features using ground-based telescopes have so far been fruitless.
