Thermal switching element and method for manufacturing the same

A method of controlling heat transfer by using a thermal switching element preparing the thermal switching element comprising:

• a first electrode;
• a second electrode;
• and
• a transition body arranged between the first electrode and the second electrode,
• wherein the first electrode has a higher temperature than the second electrode,
• the transition body comprises a material that causes an electronic phase transition by application of energy, and
• the material that causes an electronic phase transition consists essentially of an oxide with a composition expressed by SrTiO3,
• applying energy to the transition body to be an ON state, in which heat is transferred from the first electrode to the second electrode through the transition body;
• and
• cutting off the energy to the transition body to be an OFF state, in which heat is more difficult to be transferred from the first electrode to the second electrode through the transition body compared with the ON state of the transition body.
