In this work,an asymmetry waveguide photoconductivity is demonstrated for composition-graded CdS1-xSex nanobelt[1].Via changing the excitation position from the wide-bandgap(CdS0.95Se0.5)to the narrow
Inkjet printing,in the past decade,has proved to be a powerful tool in the cost-effective ambient deposition of electrodes,organic semiconductors,and plastic dielectric layers.With this patterning met
As an important Ⅲ–Ⅴ group semiconducting nanomaterial,InAs nanowires(NWs)have been reported to show great potential in ultrahigh frequency electronic nanodevices and high-performance near-infrared opt
Due to the localized surface plasmon resonances(LSPR)arising from copper deficiency,colloidal Cu2-xS(0≤x≤1)nanocrystals exhibit two well-defined optical absorption band in both of the UV-visible(300-7
It is well-known that fibers have always been applied in the textile field and very closely related to peoples daily lives.As an indispensable feature,color is more and more important for extending ap
InAs nanowires(NWs)are competitive candidates for high performance n-type devices owing to their high electron mobility,injection velocity and cylindrical geometry.However,their applications on integr
Nanofabrication technique for 10 nm T gates in high electron mobility transistors(HEMTs)is the key to achieve THz speed in microwave/THz communications.Traditional fabrication process by electron beam
We predict a magnetoresistance induced by the interfacial Rashba spin-orbit coupling in normal metal/ferromagnetic insulator bilayers.It depends on the angle between current and magnetization directio
当前中国经济进入新常态时期,一线城市中,深圳上海已经率先在总体规划中明确“建设用地零增长甚至负增长”,当前城市建设已经逐渐从增量空间扩张阶段走向存量提升的优化阶段.传统城市规划物质更新方式已很难应对城市存量街区所面临的产权、使用效率、制度等一系列复杂问题.现有制度给土地用途转变与房屋产权变更带来了巨额的交易成本,导致土地长期锁定在低效率使用者手中.本文通过持续跟踪研究厦门沙坡尾和天津小白楼五号地项
在中国城市建设发展的30年中,规划跟不上城市发展导致规划失效的例子屡屡可见,也印证了改革城市发展新理念,探究科学的研究方法,建立一个能够反映城市真实发展阶段的评价指标,以及能够全面评价城市发展水平的评价体系的重要性.因此,为了深化落实新时期首都城市战略目标,统筹衔接城市发展相关规划,有效改革规划理念,积极对城市发展进行评估,以保持规划能从宏观指导城市发展,城市发展愿景能够稳健落实.本研究以解决首都
