General description

CdSe crystal can exist in solid hexagonal or cubic structure. CdSe behaves as an n-type semiconductor, with a bandgap of 1.74 eV (300K).1

Application

Dispersions with CdS (Aldrich products 208183, 217921) deposited on glass or Si substrates results in tunable red, yellow, or green fluorescent material.[1]

Self-Assembled Nanodielectrics (SANDs) for Unconventional Electronics

Review the potential of self-assembled multilayer gate dielectric films fabricated from silane precursors for organic, inorganic, and transparent TFT and for TFT circuitry and OLED displays.

Indiscriminate adsorption of nanoparticles (NPs) significantly complicates the preparation of mesoscale NP patterns considered as enabling technology for many devices and processes.

Ultrafast time-resolved absorption spectroscopy is used to investigate exciton dynamics in CdSe nanocrystal films. The effects of morphology, quantum-dot versus quantum-rod, and preparation of nanocrystals in a thin film form are investigated. The measurements revealed longer intraband exciton relaxation in

Quantum confinement can dramatically slow down electron-phonon relaxation in nanoclusters. Known as the phonon bottleneck, the effect remains elusive. Using a state-of-the-art time-domain ab initio approach, we model the observed bottleneck in CdSe quantum dots and show that it occurs
