Phonon-Mediated Attractive Interactions between Excitons in Lead-Halide-Perovskites
Nuri Yazdani, Maryna I. Bodnarchuk, Federica Bertolotti +20
Understanding the origin of electron-phonon coupling in lead-halide perovskites (LHP) is key to interpreting and leveraging their optical and electronic properties. Here we perform…
Phase Transitions in Germanium Telluride Nanoparticle Phase-Change Materials Studied by Time-Resolved X-Ray Diffraction
Ann-Katrin U. Michel, Felix Donat, Aurelia Siegfried +6
Germanium telluride (GeTe), a phase-change material, is known to exhibit four different structural phases: three at room temperature (one amorphous and two crystalline, and …
Spectrally-resolved dielectric function of amorphous and crystalline GeTe nanoparticle thin films
Ann-Katrin U. Michel, Marilyne Sousa, Maksym Yarema +5
Phase-change materials (PCMs), which are well-established in optical and random-access memories, are increasingly studied for emerging topics such as brain-inspired computing and a…
Charge Transport in Semiconductors Assembled from Nanocrystals
Nuri Yazdani, Samuel Andermatt, Maksym Yarema +7
The potential of semiconductors assembled from nanocrystals (NC semiconductors) has been demonstrated for a broad array of electronic and optoelectronic devices, including transist…
Influence of the Surface of a Nanocrystal on its Electronic and Phononic Properties
Nuri Yazdani, Deniz Bozyigit, Kantawong Vuttivorakulchai +2
Over the past thirty years, it has been consistently observed that surface engineering of colloidal nanocrystals (NC) is key to their performance parameters. In the case of lead ch…
Non-Resonant Thermal Admittance Spectroscopy
Deniz Bozyigit, Vanessa Wood
Thermal Admittance Spectroscopy (TAS) as become a popular technique to determine trap state density and energetic position in semiconductors. In the limit of a large number of trap…
