Symmetry breaking induced activation of the nanocrystal photoluminescence

Efros, Alexander (2017-05)
We have shown that the descent of the nanocrystal symmetry from spherical to point group Cs, which is characterized by just one mirror plane symmetry element, leads step by step to activation of all five F =2, Fz= ...

Role of Surface Chemistry on Charge Carrier Transport in Quantum Dot Solids

Kagan, Cherie (2017-05)
Colloidal semiconductor quantum dots (QDs) are promising materials for electronic and optoelectronic devices due to their size tunable electronic and optical properties and the solution-based processes that enable the ...

Early Time Photoconductance in Quantum Dot Solids Probed by Ultrafast Photocurrent Spectroscopy

Klimov, Victor (2017-05)
Understanding and controlling carrier transport and recombination dynamics in colloidal quantum dot (QD) films is key to their application in electronic and optoelectronic devices. Towards this end, we have conducted ...

Electronic Transport Phenomena in Composite Nanocrystalline/Amorphous and Free-Standing Nanocrystalline Thin Films

Kakalios, James (2017-05)
Composite materials consisting of nanocrystalline semiconductors embedded within a bulk amorphous semiconductor or an insulator have attracted interest for applications ranging from photovoltaics, thermoelectrics, thin ...
