Numerical modeling of the field emission nanoscale stand-alone devices for conversion of thermal energy (T ∼ 300K) to electrical energy

New thermal field electron emission energy conversion method for vacuum electron-optical systems (EOS) with a nanostructured surface electron sources is developed. Physical and numerical modeling of an electron emission and transport processes for different EOS was carried out. Studies have shown that nanoscale thermal field emission EOS can be used to design and create stand-alone devices converting environmental thermal energy (T~300K) into electrical energy.
