Band engineering of ternary metal nitride system Ti1-x ZrxN for plasmonic applications
Mukesh Kumar, Satoshi Ishii, Naoto Umezawa +1
Chemical composition is the primary factor that determines the electronic band structure and thus also influences the optical properties of plasmonic ceramics including nitrides an…
Examining the performance of refractory conductive ceramics as plasmonic materials: a theoretical approach
Mukesh Kumar, Naoto Umezawa, Satoshi Ishii +1
The main aim of this study is to scrutinize promising plasmonic materials by understanding their electronic structure and correlating them to the optical properties of selected ref…
Computational study of the dielectric properties of [La,Sc]2O3 solid solutions
Hiroyoshi Momida, Eric Cockayne, Naoto Umezawa +1
First-principles calculations were used to compute the dielectric permittivities of hypothetical [La,Sc]2O3 solid solutions in the cubic (bixbyite) and hexagonal La2O3 phases. Diel…
