Science Daily October 5, 2018 A key element for future spin-light applications is efficient quantum information transfer at room temperature, but at room temperature the electron spin orientation is nearly randomized. This means that the information encoded in the electron spin is lost or too vague to be reliably converted to its distinct chiral light. Researchers in Sweden have devised an efficient spin-light interface. The key element of the device is extremely small disks of GaNAs, a couple of nanometres high stacked on top of each other with a thin layer of GaAs between to form chimney-shaped nanopillars. Fewer than […]

Generating energy from fluctuations of light
Phys.org March 27, 2018 Researchers in Sweden have developed a method and a material that generates an electrical impulse when the light fluctuates from sunshine to shade and vice versa. They created a tiny optical generator by combining the small antennas consisting gold nanodiscs placed on a substrate and coated with a polymeric film to create the pyroelectric properties. The antennas generate heat that is then converted to electricity with the aid of the polymer. The degree of polarisation of the polymer affects the magnitude of the generated power, while the thickness not to have any effect at all. Applications […]
A major step forward in organic electronics
Eurekalert January 11, 2018 Researchers in Sweden have shown that ladder-type polymers, such as poly(benzimidazobenzophenanthroline) (BBL), can successfully work as stable and efficient n-channel material for OECTs. BBL-based OECTs show high transconductance (up to 9.7 mS) and excellent stability in ambient and aqueous media. They have demonstrated that BBL-based n-type OECTs can be successfully integrated with p-type OECTs to form electrochemical complementary inverters. The latter show high gains and large worst-case noise margin at a supply voltage below 0.6 V. Applications of the organic components include logic circuits that can be printed on textile or paper, various types of cheap […]
