Semiconductors, which are the basic building blocks of transistors, microprocessors, lasers, and LEDs, have driven advances in computing, memory, communications, and lighting technologies since the mid-20th century.
The ultimate degree of control for engineering would be the ability to create and manipulate materials at the most basic level, fabricating devices atom by atom with precise control.
Recently, the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has cooperated with Nanjing University of Aeronautics and Astronautics and the Institute of Semiconductors of the Chinese Academy of Sciences to successfully prepare a high-quality, low-threshold single-crystal all-inorganic perovskite CsPbBr3 microcavity and obtain high temperature stability.
Perovskite based solar cells have made tremendous progress over the last decade achieving lab-scale efficiencies of 24.2% early 2019 in single-junction architecture and up to 28% in tandem (perovskite associated with crystalline silicon), turning it into the fastest-advancing solar technology to date.
With a quantum coprocessor in the cloud, physicists from Innsbruck open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics.
Physicists have demonstrated a new way to obtain the essential details that describe an isolated quantum system, such as a gas of atoms, through direct observation. The new method gives information about the likelihood of finding atoms at specific locations in the system with unprecedented spatial resolution.
Fang Xiaodong, researcher at the Laser Technology Center of Anhui Institute of Optics and Fine Mechanics, Institute of Material Science, Chinese Academy of Sciences , made new progress in using excimer laser technology to improve the performance of perovskite solar cells (PSCs ).
LASER COMPONENTS USA, specialized provider of components and services in the laser and optoelectronics industry, now also offers diodes for the NIR wavelength 940 nm in an SMD package.
D-Wave Systems Inc., the leader in quantum computing systems, software, and services, recently announced the immediate availability of a lower-noise D-Wave 2000Q processor in the Leap quantum cloud service.
Optical Surfaces Ltd. is a leading international manufacturer of high precision spherical mirrors with radii (Rc) from 25 to 5000mm (1 to 200 inches) for use in UV-Visible and Infrared applications including Schlieren imaging, wind tunnels, observatory spectrographs, bubble chambers and as hindle spheres to test hyperboloids.
