D-Band Perfect Anomalous Reflectors for 6G Applications
IEEE Access, 2021 We demonstrate anomalous reflectors at 140 GHz for the application of 6G communication coverage expansion. The reflectors are designed on cyclo-olefin polymer (COP) substrates on the basis of measured complex permittivity and conductivity at millimeter ...

Distinct topological properties in Ce monopnictides having correlated f electrons: CeN vs. CeBi
Physical Review Research, 2020 The hitherto-studied topological nature in Ce monopnictides (CePn) has been discussed based solely on their p-d band inversion, despite the existence of f electrons.

Raman spectroscopy investigations of chemically derived zigzag edge graphene nanoribbons
AIP Advances, 2013 We fabricated graphene nanoribbons (GNRs) chemically derived from expandable graphite. All GNRs exhibit atomically smooth edges that extended over their entire length. We investigated four of the fabricated GNRs using Raman spectroscopy.

The Origin of Raman D Band: Bonding and Antibonding Orbitals in Graphene
Crystals, 2013 In Raman spectroscopy of graphite and graphene, the D band at ∼ 1355 cm−1 is used as the indication of the dirtiness of a sample. However, our analysis suggests that the physics behind the D band is closely related to a very clear idea for describing a ...

DFT study on ORR catalyzed by bimetallic Pt-skin metals over substrates of Ir, Pd and Au
Nano Materials Science, 2023 Bimetallic Pt-skin catalyst is a class of near-surface alloy (NSA) that owns a high degree of control over composition. Herein, density functional theory (DFT) is used to calculate the energetics of oxygen reduction reaction (ORR) on Pt-skin over Ir, Pd ...
