Deposition of cadmium sulfide and cadmium selenide thin films using chemical bath deposition technique

William Cheung, Salvador Montes, Erik Sousa, Liangmin Zhang et autres

A simple, convenient and low cost chemical synthesis technique, chemical bath deposition, are used to deposit cadmium sulfide (CdS) and cadmium selenide (CdSe) quantum dots on glass substrates. Based our characterizations, high quality CdS and CdSe thin films have been deposited on …

Third order optical nonlinearity investigation of germanium quantum dots embedded in silica matrix

Liangmin Zhang, David Bishel, William Cheung, Joseph Mini et autres

Multilayered germanium nanocrystals embedded in silica (SiO2) matrices are fabricated by using the radio frequency magnetron co-sputtering technique. Transmission electron microscopy shows germanium (Ge) nanocrystals are confined in the (Ge+SiO2) layers in the silica thin films. Linear optical absorption coefficients at different …
