A University of Wollongong-led team has combined two traditional semiconductor doping methods to achieve new efficiencies in the topological insulator bismuth-selenide (Bi 2 Se 3), Two doping elements ...
The resulting bismuth-selenide crystals show clear ferromagnetic ordering, a large bulk band gap, high electronic mobility, and the opening of a gap of surface state making this system a good ...
Spin orbits: spiralling electrons on the surface of bismuth selenide produce circularly-polarized light. (Courtesy: iStock/VikaSuh) The first ever observations of chiral surface excitons have been ...
The research, led by Penn State University and Cornell University physicists, studies "spin torque" in devices that combine a standard magnetic material with a novel material known as a "topological ...
One of science’s newest wonder materials may find its way into computers. A study published in the July 24 Nature reveals that electrons coursing through the materials known as topological insulators ...
Tin selenide might considerably exceed the efficiency of current record holding thermoelectric materials made of bismuth telluride. However, it was thought its efficiency increased dramatically only ...
A team of researchers has developed a new material that could potentially improve the efficiency of computer processing and memory. A team of researchers led by the University of Minnesota has ...
Measurements at the BESSY II and PETRA IV synchrotron sources show that tin selenide can also be utilized as a thermoelectric material at room temperature -- so long as high pressure is applied. Tin ...
