Government-backed China Integrated Circuit Industry Investment Fund worth $47 billion will be launched soon, to improve China’s ability to design and manufacture advanced processors and CPUs. The move has been formulated to reduce the dependency on imports worth $100 billion in the semiconductor industry. It is also speculated that the funds have been increased as a result of escalating tensions between US and China following the trade impositions.

Conventional devices relied on electric fields to store information, but existing devices require large electric and magnetic fields for storing information which are difficult to produce and contain. The researchers have developed a potential solution, a new switching element made from chromia (Cr2o3). The design fuses chroma with magnetic material, which provides effective quantum coupling to Cr magnetic moments. If the device is successfully fabricated it can replace dynamic random access memory in computers.

To improve the light absorbing capability of graphene, physicists have embedded a graphene sheet within a flat photonic crystal. The physicists have shown that when the temperature of the combination changes, the potential for light absorption can be tuned. They discovered that in the case of normal light incidence, improved absorption occurs at room temperature; however, when there is an increase in temperature, the absorption peak is shifted toward the red light. The researchers concluded that it is possible to control the peak wavelength by altering the incident angle or the temperature, and also the chemical energy potential of graphene.

 

Superconducting Spin
Date
April 2018

Researchers at Cambridge University have shown that some superconductors can carry currents of spin, which is normally carried in non-superconducting, non-magnetic materials by individual electrons. The successful pairing of superconductivity and spin will result in drastic reduction in energy consumption of high performance computing. In a conventional superconductor electrons with opposite spins are paired together so that a flow of electrons carries zero spin. By creating a pure spin supercurrent , the team of researchers aims to create a super-conducting technology which could use massively less energy than the present silicon-based electronics.
