Crystal polarity
WebJul 15, 2024 · O-polar and Zn-polar ZnO films were grown by molecular beam epitaxy (MBE) on sapphire substrates. The growth process was in-situ monitored by reflection high-energy electron diffraction (RHEED). The structure, surface morphology, wettability and chemical etching properties of the polar films were characterized and compared to the … WebThe polar magnetic helical structures are considered mainly to originate from either the breaking of the space-inversion symmetry in crystal structures or the magnetic frustration (1, 4, 5). Their strong magnetism-chirality coupling triggers enormous interests in condensed matter physics, leading to many unique quantum and information ...
