Finite Element-based Nonlinear Dynamic Optimization of Nanomechanical Resonators

Autor: Li, Zichao, Alijani, Farbod, Sarafraz, Ali, Xu, Minxing, Norte, Richard A., Aragon, Alejandro M., Steeneken, Peter G.

Nonlinear dynamic simulations of mechanical resonators have been facilitated by the advent of computational techniques that generate nonlinear reduced order models (ROMs) using the finite element (FE) method. However, designing devices with specific

Quantifying stress distribution in ultra-large graphene drums through mode shape imaging

Autor: Sarafraz, Ali, Liu, Hanqing, Cvetanović, Katarina, Spasenović, Marko, Vollebregt, Sten, Garcia, Tomas Manzaneque, Steeneken, Peter G., Alijani, Farbod, Verbiest, Gerard J.

Suspended drums made of 2D materials hold potential for sensing applications. However, the industrialization of these applications is hindered by significant device-to-device variations presumably caused by non-uniform stress distributions induced by

Dynamics of pressurized ultra-thin membranes

Autor: Sarafraz, Ali, Givois, Arthur, Roslon, Irek, Liu, Hanqing, Brahmi, Hatem, Verbiest, Gerard, Steeneken, Peter G., Alijani, Farbod

The resonance frequency of ultra-thin layered two-dimensional (2D) materials changes nonlinearly with the tension induced by the pressure from the surrounding gas. Although the dynamics of pressurized 2D material membranes have been extensively explo
