Chip-Scale Aligned Chiral Carbon Nanotubes Exhibiting Giant Second Harmonic Generation
Rui Xu, Jacques Doumani, Viktor Labuntsov +16
Chiral carbon nanotubes (CNTs) are direct-gap semiconductors with optical properties governed by one-dimensional excitons with enormous oscillator strengths. Each species of chiral…
Suppression of Metallic Transport in Nitrogen-rich Two-Dimensional Transition Metal Nitrides
Hongze Gao, Da Zhou, Nguyen Tuan Hung +12
The recent experimental realization of two-dimensional (2D) transition metal nitrides (TMNs, e.g., Mo5N6, δ-MoN, and W5N6) opens new opportunities for exploring their fundamental…
Nano-Raman Spectroscopy Analysis of Nanoprotuberances in MoSe2
Jane Elisa Guimarães, Rafael Nadas, Rayan Alves +8
Contaminations in the formation of two-dimensional heterostructures can hinder or generate desired properties. Recent advancements have highlighted the potential of tip-enhanced Ra…
QR-code: An open-source program for double resonance Raman spectra
Jianqi Huang, Renhui Liu, Ye Zhang +4
We present an open-source program, QR-code, that computes double-resonance Raman (DRR) spectra using first-principles calculations. QR-code can calculate not only two-phono…
Downscaling of non van der Waals Semimetallic W5N6 with Resistivity Preservation
Hongze Gao, Da Zhou, Lu Ping +10
The bulk phase of transition metal nitrides (TMNs) has long been a subject of extensive investigation due to their utility as coating materials, electrocatalysts, and diffusion bar…
