Artificial intelligence accelerates the search for new chip materials

  • No comments
A new artificial intelligence system scans a vast space of chemical combinations and suggests gallium-based semiconductor materials with desirable electronic properties. The researchers emphasize that the materials still require experimental validation, but the method
Two-dimensional materials are considered one of the most promising directions for improving computer chips, but researchers at the Vienna University of Technology have found that some of them are unsuitable due to an underestimated physical effect. The study also points to possible alternatives. Credit: Vienna University of Technology, TU Wien.

TU Wien research published in Science points to a fundamental limitation in the interface between 2D materials and insulating layers in advanced transistors
Vials containing the new silicone copolymers, separated by chain length from longest to shortest, provide visual evidence of the changing energy gap in the new semiconductor silicon. UV illumination creates a rainbow of vials as the longer chains shift toward the red end of the electromagnetic spectrum, requiring less energy to absorb and emit light at lower energies.

A team of researchers from the University of Michigan has discovered a new silicone copolymer that can conduct electricity and emit light – a breakthrough that could lead to flexible electronics, wearable solar cells and ultra-thin color displays.
Megan MacArthur, NASA's Mission 65 pilot to the International Space Station, works in the Zero Gravity Science Glove Box and exchanges samples for an experiment called Barrier Sealed Ampoule Coagulation, or SUBSA. The physics experiment investigates experimental methods for coagulating solutions in zero gravity and is expected to lead to reduced fluid movement in the solution, Which will allow for a better distribution of the components and the potential to improve the technology used to produce semiconductor crystals.

The space agency says that the industry alone will not be able to move forward and it is required to cooperate with the government and academia. This can help solve bottlenecks that slow down progress in the field
The picture shows an energy band diagram of a micro-resonator based on a GaAs semiconductor as studied in the experiment, in which a quantum condensation of light-matter coupled quasi-particles called exciton-polaritons (exciton-polaritons) - through two-photon absorption. The achievement paves the way for new coherent control schemes and the realization of an efficient laser source in the terahertz (THz) range of electromagnetic radiation

First observation of "two-photon absorption for quantum condensation"

The achievement may accelerate research in new quantum technologies and developments in security, biological sensing, wireless communication and more
