Josephson Junction(JJ)通常采用RCSJ模型描述,但在实际器件中,结两侧超导电极、衬底及周围介质还会产生额外的分布寄生电容。若直接在三维模型中采用预设的并联 LC 参数,本征频率容易由集总 LC 共振主导,从而难以区分结本身参数与三维几何环境对频率的贡献。针对这一问题,本研究利用 COMSOL Multiphysics 建立 JJ的三维电磁模型,并通过暂时去除集总电容、保留 Josephson 电感的方式,单独识别三维结构形成的电磁模态及等效几何电容。摆脱了原先的固定共振,获得最低候选模态及其对应等效几何电容。结果说明 ... Per saperne di più
In microwave plasma chemical vapor deposition (MPCVD) reactors the microwave, plasma, flow and thermal fields are coupled in a strongly nonlinear way. The plasma reshapes the electromagnetic field in the chamber and thereby shifts the cavity resonance — by as much as 200 MHz in the case ... Per saperne di più
本文提出一种基于静电吸合效应实现真空间隙主动调制的自对准 MEMS 场发射三极管,借助多物理场耦合仿真手段系统研究该器件的机电耦合行为与场发射性能。传统纳米真空电子器件普遍面临发射极‑栅极对准难度大、电极间隙固定无法动态调控的问题,多次光刻对准不仅提升工艺复杂度,还会引入尺寸偏差劣化发射性能;同时常规器件电极间距固定,运行过程中不能动态优化电子发射条件,制约器件性能进一步提升。而 MEMS 静电吸合效应以往大多被视作应当规避的失效现象,本文将该不稳定效应转化为功能性调控机制,利用静电吸合实现阴极‑阳极真空间隙的动态可调,为解决上述难题提供新思路。 ... Per saperne di più
Underwater local dry welding is a prominent method for performing marine joints and repairs, whereas local dry-welding chambers require a stable flow of drainage gas to prevent water ingress and hydrogen diffusion, thereby ensuring weld quality. However, unstable flow, recirculation, and ... Per saperne di più
Optical tweezers enable the non-contact manipulation of micro- and nanoparticles through momentum exchange between focused optical fields and the particles, while the local energy-flow distribution plays an important role in the rotational behavior of nonspherical metallic ... Per saperne di più
Optical tweezers enable the non-contact trapping and manipulation of micro- and nanoparticles using highly localized optical fields, while the optical response of metallic nanoparticles is closely related to the spatial distribution, polarization state, and intensity of the focused light ...
