摘要：
In recent years, trap-related interfacial transport phenomena have received great attention owing to their potential applications in resistive switching devices and photo detectors. Not long ago, one new type of memristive interface that is composed of F-doped SnO_2 and Bi_2S_3 nano-network layers has demonstrated a bivariate-continuous-tunable resistance with a swift response comparable to the one in neuron synapses and with a brain-like memorizing capability. However, the resistive mechanism is still not clearly understood because of lack of evidence, and the limited improvement in the development of the interfacial device. By combining I-V characterization, electron energy-loss spectroscopy, and firstprinciple calculation, we studied in detail the macro/micro features of the memristive interface using experimental and theoretical methods, and confirmed that its atomic origin is attributed to the traps induced by O-doping. This implies that impurity-doping might be an effective strategy for improving switching features and building new interfacial memristors.
摘要：
Collective oscillations of free electrons generate plasmons on the surface of a material. A whispering-gallery microcavity effectively confines the light field on its surface based on the total reflection from its internal wall. When these two kinds of electromagnetic waves meet each other, the stimulated emissions from an individual ZnO microrod were enhanced more than 50-fold and the threshold was reduced after the whispering-gallery microcavity was coated with a monolayer of graphene and Al nanoparticles. The improvement of the lasing performance was attributed to the synergistic energy coupling of the graphene/Al surface plasmons with ZnO excitons. The lasing characteristics and the coupling mechanism were investigated systematically.

摘要：
针对传统的蚂蚁算法容易出现早熟和停滞现象,提出一种新型蚂蚁算法(new ant colony algorithm,NACA),即将转移规则、全局信息素灾变规则和局部混合调整信息素规则。选择几个典型TSP问题进行实验。研究结果表明:新型蚂蚁算法一方面提高了算法种群的多样性,同时将轮盘赌算子利用到城市转移规则中,有利于提高算法的收敛速度;另一方面,将种群个体的差分信息应用于局部信息素更新规则中,有利于搜索全局解;最后灾变算子避免算法陷入局部最优,而达到全局最优。新型的蚁群算法具有更强的搜索全局最优解的能力以及更好的稳定性和收敛性,同时为解决其他优化问题提供新的思路。
