Direct Observation of Massless Excitons and Linear Exciton Dispersion
Luna Y. Liu, Steffi Y. Woo, Jinyuan Wu +3
Excitons -- elementary excitations formed by bound electron-hole pairs -- govern the optical properties and excited-state dynamics of materials. In two-dimensions (2D), excitons ar…
Tuning color centers at a twisted interface
Cong Su, Fang Zhang, Salman Kahn +15
Color center is a promising platform for quantum technologies, but their application is hindered by the typically random defect distribution and complex mesoscopic environment. Emp…
Revealing the Brønsted-Evans-Polanyi Relation in Halide-Activated Fast MoS2 Growth Towards Millimeter-Sized 2D Crystals
Qingqing Ji, Cong Su, Nannan Mao +7
Achieving large-size two-dimensional (2D) crystals is key to fully exploiting their remarkable functionalities and application potentials. Chemical vapor deposition (CVD) growth of…
Designing Artificial Two-Dimensional Landscapes via Room-Temperature Atomic-Layer Substitution
Yunfan Guo, Yuxuan Lin, Kaichen Xie +21
Manipulating materials with atomic-scale precision is essential for the development of next-generation material design toolbox. Tremendous efforts have been made to advance the com…
Evidence for a pressure-induced phase transition of few-layer graphene to 2D diamond
Luiz G. Pimenta Martins, Diego L. Silva, Jesse S. Smith +16
We unveil the diamondization mechanism of few-layer graphene compressed in the presence of water, providing robust evidence for the pressure-induced formation of 2D diamond. High-p…
Competing dynamics of single phosphorus dopant in graphene with electron irradiation
Cong Su, Mukesh Tripathi, Qing-Bo Yan +10
Atomic-level structural changes in materials are important but challenging to study. Here, we demonstrate the dynamics and the possibility of manipulating a phosphorus dopant atom…
Tailoring exciton dynamics by elastic strain-gradient in semiconductors
Xuewen Fu, Cong Su, Qiang Fu +7
As device miniaturization approaches the atomic limit, it becomes highly desirable to exploit novel paradigms for tailoring electronic structures and carrier dynamics in materials.…
Novel Two-dimensional Carbon Allotrope with Strong Electronic Anisotropy
Cong Su, Hua Jiang, Ji Feng
Two novel two-dimensional carbon allotropes comprised of octagons and pentagons are proposed based on the first-principles calculations. The two carbon allotropes, named OPG-L and…
