The strain-stress relationships for coherent in-plane strain in heterostructures with monoclinic crystal systems: $β$ -(Al $_{x}$ Ga $_{1 - x}$ ) $_{2}$ O $_{3}$ on $(h 0 l)$ $β$ -Ga $_{2}$ O $_{3}$ as example

Mathias Schubert, Rafal Korlacki, Vanya Darakchieva

In this work we derive the state of strain or stress under symmetry conserving conditions in pseudomorphic lattices with monoclinic symmetry. We compare surface vectors across the…

The paramagnetic Lyddane-Sachs-Teller relation

Viktor Rindert, Vanya Darakchieva, Tapati Sarkar +1

In this letter, we derive an expression for magnetic dipole transitions that is analogous to the Lyddane-Sachs-Teller relation for dielectric polar lattice vibrations. We thereby d…

Bloch equations in Terahertz magnetic-resonance ellipsometry

Viktor Rindert, Steffen Richter, Philipp Kühne +3

A generalized approach derived from Blochs equation of motion of nuclear magnetic moments is presented to model the frequency, magnetic field, spin density, and temperature depende…

Effective uniaxial dielectric function tensor and optical phonons in ( $2 ˉ 01$ )-plane oriented $β$ -Ga $_{2}$ O $_{3}$ films with equally-distributed six-fold rotation domains

Alyssa Mock, Steffen Richter, Alexis Papamichail +11

Monoclinic $β$ -Ga $_{2}$ O $_{3}$ films grown on $c$ -plane sapphire have been shown to exhibit six $(2 ˉ 01)$ -plane oriented domains, which are equally-spaced-by-rotation around the su…
