    Practical Superconducting Nanowire Single-Photon Detector Sets Efficiency Record

    Researchers have demonstrated the fabrication and operation of a superconducting nanowire single-photon detector (SNSPD) with detection efficiency that they believe is the highest on record. The photodetector is made of polycrystalline NbN with system detection efficiency of 90.2 percent for 1550-nm-wavelength photons at 2.1 K. In experiments, the system detection efficiency saturated at 92.1 percent when the temperature was lowered to 1.8 K. The research team believes that [ Learn more ]

    Research breakthrough in bionic liquid-transport surface - Topological Liquid Diode

    Directed and spontaneous transport of a liquid on a solid surface is highly desired in various settings that range from microfluidics, printing, and oil-water separation to water harvesting technologies. Despite com- mendable progresses, it remains a daunting undertaking to mimic the structural and the functional sophistication inherent in living organisms in a facile and reproducible manner. Recently, Shanghai Institute of Microsystem and Information Technology (SIMIT), Chinese Academy of Sciences, in collaboration with City University of Hong Kong (CityU)[ Learn more ]

    Science publishes research of novel high speed and low power Sc-Sb-Te phase change storage material of SIMIT

    Non-volatile phase-change random-access memory (PCRAM) is regarded as a leading candidate for next-generation electronic memory hierarchy. It utilizes the pronounced electrical resistance difference between the amorphous and crystalline states of chalcogenide phase change materials (PCMs) to encode digital information. Fast and reversible phase transitions between the two states at elevated temperatures and good thermal [ Learn more ]

    The team of Prof Taohu has made important progress in transient soluble micronano optical technology

    Diffractive optical element (DOE) consists of thin micro structure patterns which change the phase of the light propagating through it. It can be used for the transformation of coherent and partially coherent light sources into desired intensity profile. Currently, DOEs are typically fabricated from inorganic constituents such as glass and some synthetic polymers. However, the lack of biocompatible (and preferably also biodegradable) building materials and the lack of facile methods for efficient functionalization greatly limits their pervasive application.[ Learn more ]
