Journal ArticleDOI
Direct measurement of the exciton binding energy and effective masses for charge carriers in organic–inorganic tri-halide perovskites
Atsuhiko Miyata,Anatolie A. Mitioglu,Paulina Plochocka,Oliver Portugall,Jacob Tse-Wei Wang,Samuel D. Stranks,Henry J. Snaith,Robin J. Nicholas +7 more
TL;DR: In this article, the exciton binding energy of perovskite solar cells was measured and it was shown that the impressive performance of solar cells arises from the spontaneous generation of free electrons and holes after light absorption.
Journal ArticleDOI
Approaching the dirac point in high-mobility multilayer epitaxial graphene.

TL;DR: Multilayer epitaxial graphene is investigated using far infrared transmission experiments in the different limits of low magnetic fields and high temperatures, finding the well-defined Landau level quantization up to room temperature at magnetic fields below 1 T, a phenomenon unusual in solid state systems.
Journal ArticleDOI
Determination of the exciton binding energy and effective masses for methylammonium and formamidinium lead tri-halide perovskite semiconductors
Krzysztof Galkowski,Krzysztof Galkowski,Anatolie A. Mitioglu,Atsuhiko Miyata,Paulina Plochocka,Oliver Portugall,Giles E. Eperon,Jacob Tse-Wei Wang,Thomas Stergiopoulos,Samuel D. Stranks,Henry J. Snaith,Robin J. Nicholas +11 more
TL;DR: In this article, the binding energy of the exciton (R*) and its reduced effective mass (μ) were investigated in the context of perovskite materials, where the excitonic states were fit as a hydrogenic atom in magnetic field and the Landau levels for free carriers to give R* and μ.
Journal ArticleDOI
Determination of the exciton binding energy and effective masses for the methylammonium and formamidinium lead tri-halide perovskite family
Krzysztof Galkowski,Anatolie A. Mitioglu,Atsuhiko Miyata,Paulina Plochocka,Oliver Portugall,Giles E. Eperon,Jacob Tse-Wei Wang,Thomas Stergiopoulos,Samuel D. Stranks,Henry J. Snaith,Robin J. Nicholas +10 more
TL;DR: In this article, the binding energy of the excitonic states of organic-inorganic halide perovskite materials has been investigated in the field of photovoltaics due to their high power conversion efficiencies.
Journal ArticleDOI
Collective vibrational modes in biological molecules investigated by terahertz time-domain spectroscopy
TL;DR: Well-resolved absorption spectra of biological molecules in the far-IR (FIR) spectral region recorded by terahertz time-domain spectroscopy (THz-TDS), which can provide a direct fingerprint of the molecular structure or conformational state of a compound.
