A micro- or nanosized electrically controlled source of optical radiation is one the key elements in optoelectronic systems. The phenomenon light emission via inelastic tunneling (LEIT) electrons through potential barriers junctions opens up new possibilities for development such sources. In this work, we present a simple approach fabrication nanoscale driven sources based on LEIT. We employ STM lithography to locally modify surface Si/Au film stack heating, which enabled by high-density tunnel current. Using proposed technique, hybrid nanoantennas with minimum diameter 60 nm were formed. Studying both electronic and properties obtained nanoantennas, confirm that resulting structures can efficiently emit photons visible range because scattering electrons. allows studying their using STM.
