چکیده

Since pivotal experimental discovery of the near-room-temperature superconductivity (NRTS) in highly-compressed sulphur hydride by Drozdov et al (2015 Nature 525 73-76), more than a dozen binary and ternary hydrogen-rich phases exhibited superconducting transition above 100 K have been discovered to date. There is widely accepted theoretical point view that primary mechanism governing emergence electron-phonon pairing. However, our recent analysis temperature dependent resistance $H_{3}S$, $LaH_{x}$, $PrH_{9}$ $BaH_{12}$ (arXiv: 2104.14145) showed these compounds exhibit dominance non-electron-phonon charge carrier interaction and, thus, it unlikely pairing for materials. Here we use same approach reveal lithium, black phosphorous, sulfur, silane. We found all superconductors interaction. This explains failure high-Tc values predicted materials first-principles calculations which utilized as Our result implies alternative mechanisms (i.e., electron-magnon, electron-polaron, electron-electron, etc.) should be tested within possible superconductors.

High-temperature Superconductivity in compressed Solid Silane

Crystal structures of silane have been extensively investigated using ab initio evolutionary simulation methods at high pressures. Two metallic structures with P2₁/c and C2/m symmetries are found stable above 383 GPa. The superconductivities of metallic phases are fully explored under BCS theory, including the reported C2/c one. Perturbative linear-response calculations for C2/m silane at 610 G...

Electron-phonon interaction and charge carrier mass enhancement in SrTiO3.

We report a comprehensive THz, infrared and optical study of Nb-doped SrTiO3 as well as dc conductivity and Hall effect measurements. Our THz spectra at 7 K show the presence of an unusually narrow (<2 meV) Drude peak. For all carrier concentrations the Drude spectral weight shows a factor of three mass enhancement relative to the effective mass in the local density approximation, whereas the s...

High charge carrier mobility and efficient charge separation in highly soluble perylenetetracarboxyl-diimides.

In this communication we report on the synthesis and charge mobility of highly soluble perylenebisimid derivatives. We show that introduction of alkylester side chains results in compounds combining a high solubility with charge mobilities up to 0.22 cm(2) V(-1) s(-1). These materials are therefore interesting as an electron acceptor for solution-processed organic photovoltaics.

Classifying Compressed Lidar Waveform Data

Full waveform recording is becoming increasingly affordable and, consequently, available in today's state-of-the-art LiDAR systems. Therefore, there is no practical limitation to the complexity of pulse detection and other methods that can be applied in post-processing mode. Analyzing the entire return signal, the full waveform can provide additional geometrical and physical information about t...
