Cooling Semiconductors with Lasers

February 21, 2013 · Print This Article

Is there anything that lasers can’t do? The latest breakthrough comes from a team of researchers at Nanyang Technological University (NTU) who have developed a method for cooling semiconductor material (cadmium sulfide) with lasers. In an editorial published in Nature, NTU reserachers report on cooling a semiconductor from 20 degrees C (68 degrees F) to -20 degrees C (-4 degrees F) as an initial proof of concept.

Heat is an unwanted side

effect of most energy-using devices. In many cases, ranging from portable electronics to medical magnetic resonance imagery equipment to scientific research equipment, the need for keeping the equipment cooled is vital to continued operate. At present, equipment such as MRI systems require liquid helium for cooling, but with laser cooling, the system could be made smaller and would not require the extensive cooling hardware that is currently needed.
