Perovskite solar cells (PSCs) are a promising photovoltaic technology but their performance remains limited by incomplete absorption of incident photons, primarily due to reflection at the transparent front electrode [1]. To address this issue, interface engineering with graphene-based ... Mehr lesen
Artificial muscles are materials or devices that mimic the motion of muscles and can change their shape and stiffness in response to external stimuli. We consider pneumatic soft actuators with fiber reinforcements designed to contract upon pressurization and mimic the motion of skeletal ... Mehr lesen
Electric forces acting on a neutral matter in divergent electric fields generate mechanical stresses even in absence of charged species. This mechanism is invoked here as a factor in solid dielectric breakdown (BD). Closed form analysis for coaxial cylinders and point-to-plane gaps is ... Mehr lesen
As reliability of transformer is highly dependable on high voltage condenser type bushing, there is need to design bushings with low dielectric stress to insure the large lifespan of components. It is analytically not possible to predict or analyze the stresses generated at foil edges, ... Mehr lesen
微纳尺度器件在芯片散热等应用中正面临严峻的传热挑战，因此需要研究材料在不同外场作用下的传热特性。本研究以 MEMS 结构为基础，构建了一种能够实现电压调控应变场的模型，以探索应变对材料热物性的影响。 我们设计了具有梳齿结构的 MEMS 模型，并在 COMSOL Multiphysics 中利用结构力学模块与 AC/DC 模块针对应变场调控进行多物理场耦合仿真（图1）。通过施加电压控制梳齿间的静电力，使器件产生应变场。由于结构复杂，直接解析计算较为困难，因此采用载荷递增法模拟不同电压下的应变分布。仿真结果表明，当电压达到约 200 V 时，梳齿结构产生约 ... Mehr lesen
Since conventional silicon metal-oxide-semiconductor field-effect transistor (MOSFET) is approaching its scaling limit, novel devices structures are being explored lately. The scaling of the technology to dimensions below ~45 nm, where short channel effects start to become significant, ... Mehr lesen
The chemisorption and absorption of CO2 bubbles have been extensively studied and modeled in literature. CO2 gas is converted into aqueous CO2, which produces OH-, HCO3- and CO32- - ions in the solution. In this study, a 3D CO2 bubble column is simulated using COMSOL Multiphysics, ... Mehr lesen
Abstract for COMSOL Conference With the world continuously scaling MOSFETs into smaller submicron dimensions, subthreshold current and threshold voltage control are important challenges to ensure optimal device performance. This study explores the effects of halo implants on simulated ... Mehr lesen
Impedance spectroscopy is an established sensing methodology used in microfluidic flow cytometry systems to electrically measure cell characteristics. The fluid transport method used in most flow cytometers is continuous flow driven by external syringe or pressure regulated pumps. An on ... Mehr lesen
