Prediction of as a Dirac Nodal Line Semimetal via First-Principles Calculations
Sophie F. Weber, Ru Chen, Qimin Yan +1
Using first-principles calculations we predict that , a previously synthesized compound, is a Dirac nodal line (DNL) semimetal. The DNL in this compound is found t…
Prediction of Ideal Topological Semimetals with Triply Degenerate Points in NaCuTe Family
Jianfeng Wang, Xuelei Sui, Wujun Shi +6
Triply degenerate points (TDPs) in band structure of a crystal can generate novel TDP fermions without high-energy counterparts. Although identifying ideal TDP semimetals, which ho…
Impact of carrier localization on recombination in InGaN quantum wells and the efficiency of nitride light-emitting diodes: insights from theory and numerical simulations
Christina Jones, Chu-Hsiang Teng, Qimin Yan +2
We examine the effect of carrier localization due to random alloy fluctuations on the radiative and Auger recombination rates in InGaN quantum wells as a function of alloy composit…
Negative Poisson's Ratio in 1T-Type Crystalline Two-Dimensional Transition Metal Dichalcogenides
Liping Yu, Qimin Yan, Adrienn Ruzsinszky
Materials with a negative Poisson's ratio, also known as auxetic materials, exhibit unusual and counterintuitive mechanical behavior - becoming fatter in cross-section when stretch…
