Half-Heusler semiconductors as piezoelectrics

, 2012
One of the central challenges in materials science is the design of functional and multifunctional materials, in which large responses are produced by applied fields and stresses. A rapidly developing paradigm for the rational design of such materials is

Pentagonal 2D Altermagnets: Material Screening and Altermagnetic Tunneling Junction Device Application

Advanced Functional Materials, EarlyView.
From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

The Multicomponent PZT-type Ceramics for Micromechatronic Applications

Archives of Metallurgy and Materials, 2017
In the paper two compositions of the multi-component PZT-type ceramics admixtures by Mn4+, Sb3+, W6+, Ni2+ were presented. The ceramic powders were synthesized by the calcination of powders while their densification was carried out by free sintering ...
