Determination of the exciton binding energy and effective masses for the methylammonium and formamidinium lead tri-halide perovskite family
Krzysztof Galkowski, Anatolie Mitioglu, Atsuhiko Miyata +8
The family of organic-inorganic halide perovskite materials has generated tremendous interest in the field of photovoltaics due to their high power conversion efficiencies. There h…
Intervalley scattering of excitons and trions in monolayer WSe under strong excitation
A. A. Mitioglu, L. Klopotowski, D. K. Maude +4
Monolayer transition metal dichalcogenides offer the possibility of optical control of the valley degree of freedom. In order to asses the potential of these materials in applicati…
Optical investigation of monolayer and bulk tungsten diselenide (WSe) in high magnetic fields
A. A. Mitioglu, P. Plochocka, Á. Granados del Aguila +5
Optical spectroscopy in high magnetic fields T is used to reveal the very different nature of carriers in monolayer and bulk transition metal dichalcogenides. In monolaye…
Direct Measurement of the Exciton Binding Energy and Effective Masses for Charge carriers in an Organic-Inorganic Tri-halide Perovskite
Atsuhiko Miyata, Anatolie Mitioglu, Paulina Plochocka +5
Solar cells based on the organic-inorganic tri-halide perovskite family of materials have shown remarkable progress recently, offering the prospect of low-cost solar energy from de…
