In-plane thermal diffusivity determination using beam-offset frequency-domain thermoreflectance with a one-dimensional optical heat source
Kai Xu, Jiali Guo, Grazia Raciti +6
We present an innovative contactless method suitable to study in-plane thermal transport based on beam-offset frequency-domain thermoreflectance using a one-dimensional heat source…
Using Pressure to Unravel the Structure-Dynamic-Disorder Relationship in Metal Halide Perovskites
Kai Xu, Luis Pérez-Fidalgo, Bethan L. Charles +3
The exceptional optoelectronic properties of metal halide perovskites (MHPs) are presumed to arise, at least in part, from the peculiar interplay between the inorganic metal-halide…
Efficient infrared sunlight absorbers based on gold-covered, inverted silicon pyramid arrays
Jinhui Hu, Luis A. Pérez, Juan Luis Garcia-Pomar +4
The transparency of silicon in the infrared region enables the design of nano/microstructures for implementation in devices to harvest the infrared (IR) part of the solar spectrum.…
Anisotropic Thermoreflectance Thermometry: A contactless frequency-domain approach to study anisotropic thermal transport
L. A. Perez, K. Xu, M. R. Wagner +6
We developed a novel contactless frequency-domain approach to study thermal transport, which is particularly convenient when thermally anisotropic materials are considered. The met…
On the role of the electron-phonon interaction in the temperature dependence of the gap of lead halide perovskites
A. Francisco-López, B. Charles, O. J. Weber +5
Lead halide perovskites are causing a change of paradigm in photovoltaics. Among other peculiarities, these perovskites exhibit an atypical temperature dependence of the fundamenta…
Towards chemically neutral carbon cleaning processes: Plasma cleaning of Ni, Rh, and Al reflective optical coatings and thin Al filters for Free Electron Lasers and synchrotron beamline applications
H. Moreno Fernández, M. Zangrando, G. Sauthier +3
The choice of a reflective optical coating or filter material has to be adapted to the intended field of application. This is mainly determined by the required photon energy range…
