Graphene-Quantum Dots Hybrid Photodetectors with Low Dark-Current Readout
D. De Fazio, B. Uzlu, I. Torre +10
Graphene-based photodetectors have shown responsivities up to 10A/W and photoconductive gains up to 10 electrons per photon. These photodetectors rely on a highly absorbi…
High Sensitivity Hybrid PbS CQD-TMDC Photodetectors up to 2 m
Onur Özdemir, Iñigo Ramiro, Shuchi Gupta +1
Recent approaches to develop infrared photodetectors characterized by high sensitivities, broadband spectral coverage, easy integration with silicon electronics and low cost have b…
Solution Processed Infrared- and Thermo- Photovoltaics based on 0.7 eV Bandgap PbS Colloidal Quantum Dots
Yu Bi, Arnau Bertran, Shuchi Gupta +6
Harnessing low energy photons is of paramount importance for multi-junction high efficiency solar cells as well as for thermo-photovoltaic applications. However, semiconductor abso…
Colloidal Quantum Dot Tandem Solar Cells Using CVD Graphene as An Atomically Thin Intermediate Recombination Layer
Yu Bi, Santanu Pradhan, Mehmet Zafer Akgul +4
Two-terminal tandem cell architectures are believed to be an effective way to further improve the power conversion efficiency in solution processed photovoltaics. To design an effi…
Image sensor array based on graphene-CMOS integration
Stijn Goossens, Gabriele Navickaite, Carles Monasterio +13
Integrated circuits based on CMOS (complementary metal-oxide semiconductors) are at the heart of the technological revolution of the past 40 years, as these have enabled compact an…
Implicit Phonon Shifts and Thermodynamical Properties of Rigid Carbon Nanotube Ropes
Shuchi Gupta, K. Dharamvir, V. K. Jindal
We calculate phonon shifts of external modes of a bunch of carbon nanotubes. A simple model based on atom-atom potential has been used to calculate the implicit anharmonicity in th…
