Prediction of phase change in pseudobinary transition metal aluminum nitrides by band parameters method

Hardness of the pseudobinary transition metal aluminum nitride (T-Al-N) films is improved with increasing the AlN content as far as the B1structure is maintained. A drastic change in the compositional dependence of the hardness corresponds to the phase change of the pseudobinary nitride from B1(NaCl) to B4(wurtzite) structure. Predicted value of AlN content for the drastic change agrees with the AlN content determined experimentally. Hardness of various T-Al-N films was closely correlated with the bulk modulus calculated from interatomic distance based on the power functional formula. The improvement of hardness is attributed to the inherent increase of bulk modulus due to dissolution of AlN into transition metal nitride.

Abstract 2D van der Waals chalcogenides such as topological insulators and transition-metal dichalcogenides and their heterostructures are now at the forefront of semiconductor research. In this paper, we discuss the fundamental features and advantages of van der Waals bonded superlattices over conventional superlattices made of 3D materials and describe in more detail one practical example, namely, interfacial phase change memory based on GeTe–Sb2Te3 superlattice structures.
