Density functional theory calculation of edge stresses in monolayer MoS
Zenan Qi, Penghui Cao, Harold S. Park
We utilize density functional theory to calculate the edge energy and edge stress for monolayer MoS nanoribbons. In contrast to previous reports for graphene, for both armcha…
FPU physics with nanomechanical graphene resonators: intrinsic relaxation and thermalization from flexural mode coupling
Daniel Midtvedt, Zenan Qi, Alexander Croy +2
Thermalization in nonlinear systems is a central concept in statistical mechanics and has been extensively studied theoretically since the seminal work of Fermi, Pasta and Ulam (FP…
Elastic Bending Modulus of Single-Layer Molybdenum Disulphide (MoS2): Finite Thickness Effect
Jin-Wu Jiang, Zenan Qi, Harold S. Park +1
We derive, from an empirical interaction potential, an analytic formula for the elastic bending modulus of single-layer MoS2 (SLMoS2). By using this approach, we do not need to def…
Resonant tunneling in graphene pseudomagnetic quantum dots
Zenan Qi, D. A. Bahamon, Vitor M. Pereira +3
Realistic relaxed configurations of triaxially strained graphene quantum dots are obtained from unbiased atomistic mechanical simulations. The local electronic structure and quantu…
