With the massive miniaturisation
of electronic components, density of the electronic components has been
enhanced significantly along with the flowing of heat which results in
overheating of the components. But conventional methods are unable to estimate
the temperature in the electronic components due to limitation imposed by size
of it.
Researchers have recently devised
a solution of the above issue by fabricating a molecular film and using it in an
electronic component of a nanometric scale. The film is made by spin crossover
molecules, a temperature sensitive molecule, which is extremely stable even
after several uses. Due to the bi-stability property of these molecules, these
molecules exist into two electronic states with difference physical property and
interchange the states by absorbing and loosing energy.
Once deposited in the form of a
film on an electronic component, the optical properties of SCO molecules change
depending on the temperature, enabling this chemical thermometer to establish a
nanometric-scale thermal map of the surface of microelectronic circuits. The
devise will soon be sued at industrial scale with improved design.
