Strain-Tunable Opto-electronics in PdS Monolayer: the Role of Band Nesting and Carrier-Phonon Scattering
Hongfa Wang, Yancheng Gong, Subrahmanyam Pattamatta +3
Strain engineering is a powerful strategy for tuning the optoelectronic properties in two-dimensional materials, yet the underlying mechanisms governing their strain response are o…
Hot-electron-injection-induced symmetry breaking in bilayer MoS probed by second-harmonic generation
Zhizi Guan, Zhiwei Peng, David J. Srolovitz +2
Symmetry governs the selection rules of light-matter interactions in crystalline materials, making symmetry manipulation a powerful tool for tuning their optical properties. Here,…
Electron hopping induced phonon pumping in opto-mechanical molecular nanocavities
Yu Bai, Ilya Razdolski, Zhizi Guan +5
Plasmonic molecular nanojunctions exhibit opto-mechanical coupling at the nanoscale, enabling intertwined optical, vibrational and electronic phenomena. Here, we demonstrate plasmo…
Strain-Enabled Giant Second-Order Susceptibility in Monolayer WSe
Zhizi Guan, Yunkun Xu, Junwen Li +3
Monolayer WSe (ML WSe) exhibits a high second-harmonic generation (SHG) efficiency under single 1-photon (1-p) or 2-photon (2-p) resonant excitation conditions due to enhan…
Tuning nanoscale adhesive contact behavior to a near ideal Hertzian state via graphene coverage
Yongchao Chen, Zhizi Guan, Yongtao Yao +1
We carry out molecular statics (MS) simulations to study the indentation process of Pt (111) surfaces using an indenter with the radius of 5-20 nm. The substrate and indenter surfa…
