Contact-free Electrical Characterisation of Novel Materials Using Terahertz Spectroscopy
… (InAs), indium arsenide phosphide (InAsP) and tin-based halide perovskites were extensively studied using terahertz spectroscopy. An ultra-thin InP layer with a ∼2- 3 nm thickness and a higher band gap in comparison, has been utilised to passivate and suppress the detrimental effect of the …

Mixed Lead-Tin Halide Perovskites for Optoelectronic Applications
Mixed lead-tin (Pb-Sn) perovskites are unique materials in the family of halide perovskites. Unlike Pb perovskites, these mixed-metal systems can demonstrate bandgaps below 1.3 eV and are therefore essential constituents for low bandgap bottom subcell in all-perovskite tandem solar cells as well as …
