Cubic boron arsenide – the next wonder semiconductor

Oct 25, 2022 (Nanowerk News) In a study that confirms its promise as the next-generation semiconductor material, UC Santa Barbara researchers have directly visualized the photocarrier transport properties of cubic boron arsenide single crystals. “We were able to visualize how the charge moves in our sample,” said Bolin Liao, an...

Researchers create first quasiparticle Bose-Einstein condensate

Oct 25, 2022 (Nanowerk News) Scientists have created a Bose-Einstein condensate out of excitons — quasiparticles that combine electrons and positively charged “holes” — in a semiconductor. Quasiparticle Bose-Einstein condensates have for six decades been something of a holy grail of low-temperature physics. Physicists have created the first Bose-Einstein condensate...

Energetic winds blow from the Triangulum Galaxy

Oct 25, 2022 (Nanowerk News) Galaxies are systems of stars and interstellar gas in interaction. Observations show that galax-ies today are forming fewer stars than they did in the past. As cold gas is needed to form stars, models link the deceleration of star formation and the observed evolution of...
