Fingerprints of Excitonic Collective Modes in the Two-Dimensional Electron Gas
Jakob Wolff, Silvana Botti, Lucia Reining +1
The two-dimensional homogeneous electron gas (2D HEG) is a prototype system of fundamental interest that can be realized experimentally over a wide range of densities. Here, we inv…
Prediction of high-Tc superconductivity in ternary actinium beryllium hydrides at low pressure
Kun Gao, Wenwen Cui, Jingming Shi +5
Hydrogen-rich superconductors are promising candidates to achieve room-temperature superconductivity. However, the extreme pressures needed to stabilize these structures significan…
Determination of acoustic phonon anharmonicities via second-order Raman scattering in CuI
Ron Hildebrandt, Michael Seifert, Janine George +5
We demonstrate the determination of anharmonic acoustic phonon properties via second-order Raman scattering exemplarily on copper iodide single crystals. The origin of multi-phonon…
Transfer learning on large datasets for the accurate prediction of material properties
Noah Hoffmann, Jonathan Schmidt, Silvana Botti +1
Graph neural networks trained on large crystal structure databases are extremely effective in replacing ab initio calculations in the discovery and characterization of materials. H…
First-principles insight in structure-property relationships of hexagonal Si and Ge polytypes
Martin Keller, Abderrezak Belabbes, Jürgen Furthmüller +2
Hexagonal SiGe is a promising material for combining electronic and photonic technologies. In this work, the energetic, structural, elastic and electronic properties of the hexagon…
Effects of hole doping on the electronic and optical properties of transparent conducting copper iodide
Michael Seifert, Miguel A. L. Marques, Silvana Botti
Zincblende copper iodide has been attracting growing interest as p-type semiconductor for applications in transparent electronics and transparent thermoelectrics. A key step toward…
