DOI: 10.1002/adma.202200221

Abstract: There are significant applications for miniature on‐chip spectrometers in many fields. However, at present, on‐chip spectrometers have to utilize an integrated strategy to achieve spectral analysis, which undoubtedly squanders the photosensitive area and adds pressure… read more here.

DOI: 10.1016/j.tsf.2020.138012

Abstract: Abstract Clear Coulomb blockade characteristics of Fe nanodots in a multiple-nanodot array were achieved. The array was fabricated in a self-assembled manner by Fe deposition between the source and drain electrodes on thermally-grown SiO2/Si substrates.… read more here.

DOI: 10.1038/s41563-018-0254-7

Abstract: The application of colloidal semiconductor quantum dots as single-dot light sources still requires several challenges to be overcome. Recently, there has been considerable progress in suppressing intensity fluctuations (blinking) by encapsulating an emitting core in… read more here.

DOI: 10.1063/5.0223989

Abstract: High-pressure water vapor annealing (HWA) was recently demonstrated as a method that can substantially improve the photoluminescence quantum yield (PLQY) of silicon quantum dots (Si QDs) with the oxide shell. In this Letter, the mechanism… read more here.
