Researchers at CEA/CNRS/Université Paris Saclay, University College London and ETH Zurich have recently devised a new method to control the temperature of a spin ensemble by increasing electron spin polarization above its ...
Light can generate an electrical current in semiconductor materials. This is how solar cells generate electricity from sunlight and how smart phone cameras can take photographs. To collect the generated electrical current, ...
