Advancing Noise-Resilient Twist Angle Characterization in Bilayer Graphene through Raman Spectroscopy via GAN-CNN Modeling
Dan Hu, Ting-Fung Chung, Yong P. Chen +1
In this study, we introduce an innovative methodology for robust twist angle identification in bilayer graphene using Raman spectroscopy, featuring the integration of generative ad…
Real-space imaging of the tailored plasmons in twisted bilayer graphene
Fengrui Hu, Suprem R Das, Yilong Luan +3
We report a systematic plasmonic study of twisted bilayer graphene (TBLG) - two graphene layers stacked with a twist angle. Through real-space nanoimaging of TBLG single crystals w…
Strain-stress study of AlxGa1-xN/AlN heterostructures on c-plane sapphire and related optical properties
Y. Feng, V. Saravade, T. F. Chung +5
This work presents a systematic study of stress and strain of AlxGa1-xN/AlN with composition ranging from GaN to AlN, grown on a c-plane sapphire by metal-organic chemical vapor de…
Transport measurements in twisted bilayer graphene: Electron-phonon coupling and Landau level crossing
Ting-Fung Chung, Yang Xu, Yong P. Chen
We investigate electronic transport in twisted bilayer graphene (tBLG) under variable temperatures (), carrier densities (), and transverse magnetic fields, focusing on sampl…
Electrical spin injection into graphene from a topological insulator in a van der Waals heterostructure
Jifa Tian, Ting-Fung Chung, Ireneusz Miotkowski +1
All-electrical (magnetic-material-free) spin injection is one of the outstanding goals in spintronics. Topological insulators (TIs) have been recognized as a promising electrically…
Experimental Observation of Two Massless Dirac-Fermion Gases in Graphene-Topological Insulator Heterostructure
Guang Bian, Ting-Fung Chung, Chang Liu +19
Graphene and topological insulators (TI) possess two-dimensional Dirac fermions with distinct physical properties. Integrating these two Dirac materials in a single device creates…
