Complete Raman Tensor Determination in Birefringent -GaO by Single-Stage Hyperspectral Analysis of Polarization Angle-Resolved Raman Spectra
Hans Tornatzky, Jonas Rose, Moritz MeiÃner +5
The low symmetry of the monoclinic phase of GaO leads to pronounced optical anisotropy and, consequently, to birefringence, which strongly affects the Raman response. Becau…
Molecular Beam Epitaxy of AlScN Nanowires: Towards Group-III Nitride Piezoelectric Nanogenerators with Enhanced Response
Adriano Notarangelo, Rudeesun Songmuang, Mostafa Saleh +10
The paper reports the molecular beam epitaxy growth of Al₁₋ₓScₓN nanowires with controlled Sc content, integrates them into vertical piezoelectric nanogenerators, and demonstrates…
Lattice dynamics and complete polarization analysis of Raman-active modes in LaInO
Jonas Rose, Hai Nguyen, Moritz MeiÃner +7
In this study, we present a comprehensive analysis of the Raman active phonon modes in orthorhombic LaInO based on a combination of polarization-angle resolved Raman spectrosco…
Microscopic Origin of Temperature-Dependent Anisotropic Heat Transport in Ultrawide-Bandgap Rutile GeO2
Pouria Emtenani, Marta Loletti, Felix Nippert +7
Ultrawide-bandgap rutile GeO2 is emerging as a promising semiconductor for power electronics, where efficient heat dissipation is essential to suppress self-heating and ensure devi…
