The unusual discovery made at low temperatures

Scientists from the Low Temperature Laboratory of Helsinki University of Technology investigated the heat transfer between two small metal samples, coupled superconductor. They found that at very low temperatures heat is distributed via electromagnetic radiation, reported EurekAlert. Dr. Matthias Bags (Matthias Meschke), prof. Jukka Pekola (Jukka Pekola) and their colleagues studied the spread of heat in the micro-devices and nanorazmera based on conventional silicon chips, at a temperature of 0.1 degrees above absolute zero. During the study, scientists found that at very low temperatures heat is distributed through the superconductor through the electromagnetic radiation. At the same coefficient of thermal conductivity can only accept a strictly defined quantum values. To measure the temperature of the sample, which is only 100 nm in cross section,

fixed tunneling current from its surface. As the value of tunneling current determines the distribution of energy and temperature of electrons. The fundamental phenomenon that scientists watched, does not have immediate practical applications. However, this effect should be taken into account in the design of sensitive radiation detectors for astronomical observations, for which work at very low temperatures will significantly influence the heat exchange with the environment.
