Published in 2017 at "Journal of Alloys and Compounds"

DOI: 10.1016/j.jallcom.2017.04.109

Abstract: Abstract We investigated quantized-charge and energy transfer at the pentacene/lead sulfide (PbS) interface through realization of PbS nanocrystal (NC) size-dependent quantum confinement effect, providing insights into the presence of triplet exciton dissociation and energy transfer.… read more here.

Published in 2017 at "Journal of the American Chemical Society"

DOI: 10.1021/jacs.6b12878

Abstract: Excitonic effects, arising from the Coulomb interactions between photogenerated electrons and holes, dominate the optical excitation properties of semiconductors, whereas their influences on photocatalytic processes have seldom been discussed. In view of the competitive generation… read more here.

Published in 2021 at "Nanoscale"

DOI: 10.1039/d0nr07131e

Abstract: Monolayers of transition metal dichalcogenides (TMDs) have been established in the last years as promising materials for novel optoelectronic devices. However, the performance of such devices is often limited by the dissociation of tightly bound… read more here.

Published in 2017 at "AIP Advances"

DOI: 10.1063/1.4975224

Abstract: Exciton dissociation energy was obtained based on the comparison of thickness of the space charge region estimated from the measurement of capacitance of prepared Schottky diode and from the measurement of photovoltage spectra. While the… read more here.

Published in 2023 at "Physical Review B"

DOI: 10.1103/physrevb.107.195121

Abstract: It is well known that phonons can overscreen the bare Coulomb electron-electron repulsion, turning it into the effective attraction that binds the Cooper pairs responsible for BCS superconductivity. Here, we use a simple lattice model… read more here.
