Tuning the Interlayer Microstructure and Residual Stress of Buffer-Free Direct Bonding GaN/Si Heterostructures
Yan Zhou, Shi Zhou, Shun Wan +8
The direct integration of GaN with Si can boost great potential for low-cost, large-scale, and high-power device applications. However, it is still challengeable to directly grow G…
Raman spectroscopic characterization of stacking configuration and interlayer coupling of twisted multilayer graphene grown by chemical vapor deposition
Jiang-Bin Wu, Huan Wang, Xiao-Li Li +2
Multilayer graphene (MLG) grown by chemical vapor deposition (CVD) is a promising material for electronic and optoelectronic devices. Understanding the stacking configuration and i…
Raman spectroscopy at the edges of multilayer graphene
Q. -Q. Li, X. Zhang, W. -P. Han +4
Edges naturally exist in a single-layer graphene sample. Similarly, individual graphene layers in a multilayer graphene sample contribute their own edges. We study the Raman spectr…
Strong Photoluminescence Enhancement of MoS2 through Defect Engineering and Oxygen Bonding
Haiyan Nan, Zilu Wang, Wenhui Wang +9
We report on a strong photoluminescence (PL) enhancement of monolayer MoS2 through defect engineering and oxygen bonding. Micro- PL and Raman images clearly reveal that the PL enha…
Robust optical emission polarization in MoS2 monolayers through selective valley excitation
G. Sallen, L. Bouet, X. Marie +8
We report polarization resolved photoluminescence from monolayer MoS2, a two-dimensional, non-centrosymmetric crystal with direct energy gaps at two different valleys in momentum s…
