In this paper, two-dimensional （2D） transient simulations of an A1GaN/GaN high-electron-mobility transistor （HEMT） are carded out and analyzed to investigate the current collapse due to trapping effects. The coupling effect of the trapping and thermal effects are taken into account in our simulation. The turn-on pulse gate-lag transient responses with different quiescent biases are obtained, and the pulsed current-voltage （l-V） curves are extracted from the transients. The experimental results of both gate-lag transient current and pulsed I-V curves are reproduced by the simulation, and the current collapse due to the trapping effect is explained from the view of physics based on the simulation results. In addition, the results show that bulk acceptor traps can influence the gate-lag transient characteristics of A1GaN/GaN HEMTs besides surface traps and that the thermal effect can accelerate the emission of captured electrons for traps. Pulse transient simulation is meaningful in analyzing the mechanism of dynamic current collapse, and the work in this paper will benefit the reliability study and model development of GaN-based devices.

在认定偷换商家二维码案件的性质问题上,存在诈骗罪、盗窃罪、三角盗窃罪三种主要观点。实际上此种案件并不满足诈骗罪的犯罪构成要件。在传统刑法理论中,盗窃罪中财物所有人往往和受害人是一体的,但现实中也存在财物所有人与受害人相分离的状况,此即三角盗窃,在这种盗窃行为中,行为人采用秘密窃取的方式,将本属商家的财产性利益转移占为己有,符合盗窃罪的特征,应认定为盗窃罪。

酒西盆地位于阿尔金左旋走滑断裂和北祁连断裂相交的三角地区,对研究青藏高原北缘新生代早期构造—沉积演化具有重要意义。通过研究酒西盆地红柳峡剖面和火烧沟剖面始新统火烧沟组砂岩碎屑组分类型、形态及石英阴极发光特征,发现大量岩屑、长石和石英颗粒具有明显的变质岩来源特征,认为火烧沟组物源为变质岩。结合酒西盆地地质构造背景及盆地NW向古水流特征,通过系统分析该盆地周缘可提供物源的高点(阿尔金山、祁连山)区域岩性特征,认为酒西盆地火烧沟组物源来自阿尔金山,推测阿尔金左旋走滑断裂的断距应>450km。

Natural swarms arranged from cells to herds are usually decentralized but display intriguing collective intelligence in coordinating individuals across large scales to efficiently achieve their common goals. Learning from nature may provide new strategies for controlling collective dynamics of synthetic swarms to accomplish specific functions. Here, we present a bioinspired computational framework that steers distributed active swarms to collectively capture and merge targets via reinforcement learning. We exploit collective milling structures of natural herds to cage the targets, and adopt a switching control policy inspired by sperms' chiral dynamics to optimize the trajectories of individuals, through which the active swarms can selforganize to enclose single or multiple distant targets in a dynamical, adaptive and scalable manner. There exists a critical swarm size, beyond which the excessive competition between agents would generate large mechanical forces, leading to capture instability but enabling the transition from short-distance to long-distance merging capture of multiple targets. This work provides physical insights into distributed active swarms and could offer a multilevel, decentralized strategy toward controlling swarm robotics in wide applications such as bio-medical devices, machine immunity, and target clearance.
