Description
Quantum confinement that semiconductors experience at the nanoscale facilitate the creation of multiexcitons. However, this same confinement also increases the efficiency of Auger recombination which result in low quantum yields from these states....

Description
Colloidal semiconducting quantum dots (QDs) are ideal candidates for optoelectronic devices such as solar cells and LEDs because of their high photoluminescence (PL) quantum yields and photostability. In order to improve device efficiencies, we mu...

Description
The organic semiconductor 2,2’,7,7’-tetrakis-(N,N-di-p-methoxyphenylamine)9,9’-spirobifluorene (Spiro-OMeTAD) contact properties are studied on p-, n-, and n+-type silicon. Spiro-OMeTAD is a solid state hole conductor that has notably been used in...
