Field-induced light emission from a close-packed Mn-doped ZnS quantum-dot layer in an alternate-current thin-film electroluminescent configuration

Quantum current modeling in nano-transistors with a quantum dot

Carbon quantum dots (CQDs) serve as a new class of ‘zero dimensional’ nanomaterial’s in thecarbon class with sizes below 10 nm. As light emitting nanocrystals, QDs are assembled from semiconductormaterials, from the elements in the periodic groups of II-VI, III-V or IV-VI, mainly thanks to impacts of quantum confinement QDs have unique optical properties such as brighter, highly pho...

Photo-induced charge and luminescence measurements of evaporated ZnS:Mn alternating-current thin-film electroluminescent devices

B. A. Cleary P. D. Keir J. C. Hitt T. K. Plant* J. F. Wager* S. S. Sun* Abstract — Photo-induced charge (PIQ) and photo-induced luminescence (PIL) measurements are employed for the characterization of evaporated ZnS:Mn alternating-current thin-film-electroluminescent (ACTFEL) devices. PIQ and PIL measurements involve monitoring the charge and luminescence associated with the transport of UV-exc...

Field-emission from quantum-dot-in-perovskite solids

Quantum dot and well architectures are attractive for infrared optoelectronics, and have led to the realization of compelling light sensors. However, they require well-defined passivated interfaces and rapid charge transport, and this has restricted their efficient implementation to costly vacuum-epitaxially grown semiconductors. Here we report solution-processed, sensitive infrared field-emiss...
