WebThe bandgap of ReS 2 amounts to ~1.4 eV which corresponds to an optical absorption at ~800 nm wavelength . Nonetheless, previous works have reported generation of Q … WebThe advent of imagers based on wide-bandgap materials will permit new observations and, by simplifying their design, cheaper instruments. As for the Solar Orbiter, the aspiration for wide-bandgap material (WBGM) based UV detectors is still more sensible because the spacecraft will approach the Sun where the heat and the radiation fluxes are high.
WebThe bandgap of ReS 2 amounts to ~1.4 eV which corresponds to an optical absorption at ~800 nm wavelength . Nonetheless, previous works have reported generation of Q-switched and mode-locked lasers using ReS 2 functioning as SA at 1550 nm (~0.8 eV) and 2950 nm (~0.4 eV), which is much less than the bandgap of ReS 2 .
