Improving the utilization of solar spectra of wide bandgap semiconductors that can potentially provide enough free energy is one of the promising strategies for realizing efficient and spontaneous integrated conversion of solar energy to chemical fuels. We demonstrate herein that nitrogen doped InP quantum dots (QDs) embedded in wide bandgap GaP could improve the solar energy conversion performance...
Recently a new photodetector design based on quantum dots and resonant-tunneling diode (QDRTD) was proposed by Shields et al. which demonstrated high detection efficiency and a resolution to the single photon level. Different from the avalanche photo diode (APD) based photodetector, the detection mechanism of this device is to sense the change of the resonant tunneling current across the double barrier...
A novel design of photodetector device based on GaN double barrier resonant tunneling diode (DBRTD) coupled with a layer of colloidal quantum dots embedded in conductive polymer is proposed. The current-voltage characteristic of this new photon detector is calculated using the double-barrier quantum well (DBQW) model for different temperatures and widths of the well of the RTD. Possible effect of...
