A visible‐to‐infrared miniaturized indium selenide spectrometer enabled by a gate‐tunable spectral response matrix

InfoScience, EarlyView.
Traditional light‐analyzing tools, known as spectrometers, are typically too bulky and expensive to fit into portable electronics like smartphones or wearables. In this study, we developed a microscopic, high‐performance spectrometer using a material called Indium Selenide combined with smart algorithms to accurately analyze light from the visible to ...
