Studies on the Preparation, Immobilization, and Luminescence Properties of Zinc Oxide (ZnO)Quantum Dots
<p>Quantum dots are a part of very important our technological future because of their intriguing and useful properties. These properties are different in character from those of the corresponding bulk material. Quantum dots are inorganic artificial semiconductor nanocrystal whose electrons …

GRAPHENE BASED DUAL FUNCTIONAL, SELF-POWERED PHOTODETECTOR FOR DAILY UV SENSING
ZnO quantum dots have been widely used for ultraviolent photodetectors. However, the relatively low responsivity limits the practical application. New 2D materials incorporated with quantum dots heterostructure are emerging to improve the performance of photodetector. In this work, three types of …

Exploring and exploiting charge-carrier confinement in semiconductor nanostructures : heterodimensionality in sub-monolayer InAs in GaAs and photoelectrolysis using type-II heterojunctions
… In-rich agglomerations within a lateral InGaAs quantum well (QW) with lower In content. Low-temperature photoluminescence (PL) and magneto-PL reveals strong vertical and weak lateral confinement, indicative of a two-dimensional (2D) excitons. Paradoxically, high-temperature magneto-PL allows …
