Electronic and structural characterisation of Cu3BiS3 thin films for the absorber layer of sustainable photovoltaics [PDF]

, 2014
Thin films of p-type Cu3BiS3 with an orthorhombic wittichenite structure, a semiconductor with high potential for thin film solar cell absorber layers, were synthesised by thermal annealing of Cu and Bi precursors, magnetron sputtered on Mo/glass ...

Effect of Doping on the Bandgap of the Organic–Inorganic Hybrid Ferroelectric Material [C₆N₂H₁₈]Bi_1−xSb_xI₅ (0.0 < x < 1.0)

Applied Sciences, 2022
The rapidly developing organic–inorganic hybrid chalcogenide solar cells have now become a hot topic of interest. However, the bandgap of inorganic ferroelectric materials with a typical chalcogenide structure is too wide to match the solar spectrum ...

Rational design of Bi-doped rGO/Co3O4 nanohybrids for ethanol sensing [PDF]

, 2021
Gas sensors based on metal oxide semiconductors (MOSCs) and reduced graphene oxide (rGO) for sensing of organic volatile compounds often suffer from high operation temperature, low responses, poor selectivity, or narrow detection range. Herein, we design

Continuous wave and modelocked femtosecond novel bulk glass lasers operating around 2000 nm

, 2011
This thesis reports on the development of glass-based femtosecond laser sources around 2 µm wavelength. In order to be able to produce 2 µm radiation the dopants used were trivalent Thulium (Tm³⁺) and trivalent Holmium (Ho³⁺) that could be optically ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.
