Dielectric confinement of excitons in type-I and type-II semiconductor nanorods
Institute of Physics (2011-01-12)We theoretically study the effect of the dielectric environment on the exciton ground state of CdSe and CdTe/CdSe/CdTe nanorods. We show that insulating environments enhance the exciton recombination rate and blueshift the ... -
Dilemmas of dye-sensitized solar cells
Wiley-VCH Verlag Berlin (2011)Ferrocene to the rescue: The dye-sensitized solar cell allows changes in the energetics of electron transport, molecular absorbers, and hole transport materials to better harvest the energy of solar photons (see picture). ... -
Dopant segregation analysis on Sb:SnO2 nanocrystals
Wiley (2011-08-26)The development of reliable nanostructured devices is intrinsically dependent on the description and manipulation of materials properties at the atomic scale. Consequently, several technological advances are dependent on ... -
Origin of two-hole triplet splitting in circular quantum dots
Elsevier (2012-05)Recent photoluminescence spectra of positively charged excitons in InAs/GaAs quantum dots have revealed the existence of large splittings between the View the MathML sourcep-shell triplet sublevels of holes. We provide an ...
