Q-dots for Optoelectronics

We use new semiconductor nanocrystals to assemble materials for next generation optoelectronic applications. The particles have sizes small enough to exhibit quantum confinement effects, leading to quantization of electronic states. Assembled into supercrystals, this can lead to new collective electronic states (energy bands), similar to atomic crystals, with band-like electronic transport. We focus on three main systems:

We use recently discovered inorganic perovskite nanocrystals to assemble highly ordered cubic supercrystals for photovoltaic films. Read more …

We use well-established CdSe and CdTe nanocrystals to assemble dense superstructures and investigate their resulting optoelectronic properties.

We investigate ball-milled silicon nanocrystals that, despite the indirect band gap of silicon, exhibit strong photoluminescence.
