Magnetic-Order-Driven Nonlinear Photocurrents in PT-Broken Antiferromagnetic MnS2 and Altermagnetic MnSe2
Fu Li, Rajyavardhan Ray, Xiaoxiong Liu +6
Nonlinear photocurrent responses generally require inversion-symmetry breaking, but its origin can be magnetic rather than structural. In this study, we investigate the bulk photov…
Fermi energy Weyl nodes in Te (=Ta, Nb, =Ir, Rh)
Shivam Parasar, Jeroen van den Brink, Rajyavardhan Ray
Key aspects of the quantum oscillations and magnetoresistance in Weyl semimetals Te (=Nb,Ta, =Rh, Ir) persist as open questions, obscuring the link between their topo…
Electronic structure fingerprints of visible-range excitons in double perovskite oxides
Bhagyashree Behera, Debatri Ash, Urmimala Dey +6
Presence of excitons significantly influence the optoelectronic properties and potential applications of materials. Using combined theoretical and experimental tools, we investigat…
Layer dependent topological phases and transitions in TaRhTe: From monolayer and bilayer to bulk
Xiao Zhang, Ning Mao, Oleg Janson +2
The recently synthesized ternary quasi-2D material TaRhTe is a bulk Weyl semimetal with an intrinsically layered structure, which poses the question how the topology of its ele…
Correlation between electronic polarization and shift current in cubic and hexagonal semiconductors LiZn ( = P, As, Sb)
Urmimala Dey, Jeroen van den Brink, Rajyavardhan Ray
The rectified bulk photovoltaic effect (BPVE) in noncentrosymmetric semiconductors, also called shift current, is considered promising for optoelectronic devices, terahertz emissio…
Evolution of electronic and magnetic properties of SrIrO under strain
Ekaterina M. Parschke, Wei-Chih Chen, Rajyavardhan Ray +1
Motivated by properties-controlling potential of the strain, we investigate strain dependence of structure, electronic and magnetic properties of SrIrO using complementary…
