A group of researchers at the Niels Bohr Institute has announced on a proud note that they have successfully combined two exciting worlds of nano technology and quantum physics to come up with a new, revolutionary technology.
By combining the two distinct units of modern physics, the researchers managed to invent a new method of laser cooling semiconductor membranes.
Semiconductors happen to be one of the most crucial components in almost any electronic product including LEDs, solar cells and many more. Also, an efficient cooling methodology of electronic components is vital when it comes to next-generation technologies such as future ultrasensitive sensors and quantum computers.
According to the researchers, the new cooling technique involves a rather unique approach as it paradoxically heats-up the material. By the use of lasers, they managed to cool membrane fluctuations to minus 269 degrees C.
"In experiments, we have succeeded in achieving a new and efficient cooling of a solid material by using lasers. We have produced a semiconductor membrane with a thickness of 160 nanometres and an unprecedented surface area of 1 by 1 millimetre," the researchers said in a statement.
"In the experiments, we let the membrane interact with the laser light in such a way that its mechanical movements affected the light that hit it," they added.
