Physical and Numerical Modeling of the Stand-Alone Nanoscale Electrical Energy Generator Operating On the Bases of Abnormal Thermal Field Emission Phenomenon at Room Temperature

Abnormal thermal field electron emission energy conversion method for vacuum electron-optical systems (EOS) with a nanostructured surface electron sources is offered and developed. Physical and numerical modeling of an electron emission and transport processes for different EOS is carried out. It is shown that at the specific configuration of electrostatic and magnetic fields in the EOS offered method permits to design high efficiency energy conversion devices. Studies have shown that nano- and microstructured field emission systems can be used to design and create stand-alone devices converting environmental thermal energy (T similar to 300K) into electrical energy.
