Complete Raman Tensor Determination in Birefringent -GaO by Single-Stage Hyperspectral Analysis of Polarization Angle-Resolved Raman Spectra
Hans Tornatzky, Jonas Rose, Moritz Meißner +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…
Lattice dynamics and complete polarization analysis of Raman-active modes in LaInO
Jonas Rose, Hai Nguyen, Moritz Meißner +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…
Spectral tuning of hyperbolic shear polaritons in monoclinic gallium oxide via isotopic substitution
Giulia Carini, Mohit Pradhan, Elena Gelzinyte +26
Hyperbolic phonon polaritons - hybridized modes arising from the ultrastrong coupling of infrared light to strongly anisotropic lattice vibrations in uniaxial or biaxial polar crys…
Epitaxial growth and characterization of multi-layer site-controlled InGaAs quantum dots based on the buried stressor method
Imad Limame, Ching-Wen Shih, Alexej Koltchanov +8
We report on the epitaxial growth, theoretical modeling, and structural as well as optical investigation of multi-layer, site-controlled quantum dots fabricated using the buried st…
Tackling Disorder in -GaO
Laura E. Ratcliff, Takayoshi Oshima, Felix Nippert +19
GaO and its polymorphs are attracting increasing attention. The rich structural space of polymorphic oxide systems such as GaO offers potential for electronic struc…
