Latest Patents
One of Tsakadze's latest patents is titled "Liquid metal contact as possible element for thermotunneling." This invention investigates the use of liquid metal contacts for devices based on thermotunneling. The electric and thermal characteristics of low wetting contact Hg/Si and high wetting contacts Hg/Cu were determined and compared. Tunneling I-V characteristics for Hg/Si were obtained, while for Hg/Cu, I-V characteristics were ohmic. The tunneling I-V characteristic is explained by the presence of a nanogap between the contact materials. Heat conductance of high wetting and low wetting contacts were compared using calorimeter measurements, revealing that the heat conductance of high wetting contact was 3-4 times more than that of low wetting contact. Both electric and thermal characteristics of liquid metal contact indicated its potential use for thermotunneling devices. To further enhance the suitability of liquid metal for room temperature cooling, cesium (Cs) was dissolved in liquid mercury (Hg), achieving a work function as low as 2.6 eV.
Another significant patent is "Method for increasing efficiency of thermotunnel devices." This invention comprises a tunneling device in which the collector electrode is modified to enhance the tunneling of higher energy electrons from the emitter electrode to the collector electrode. In one embodiment, the collector electrode is contacted with an insulator layer, preferably aluminum oxide, placed between the collector and emitter electrodes. This method aims to improve the efficiency of tunneling devices significantly.
