Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...

Although time-stretch spectroscopy is an emerging ultrafast spectroscopic technique, the applications in industrial fields have been limited due to the low output power caused by undesirable nonlinear ...

Perovskite photodetectors are fabricated using indium-tin-oxide-coated mica plates as the transparent electrode. The thickness of the indium tin oxide film is 135 nm. Then, a SnO 2 film is spin coated ...
