We report electrically-induced, explosive atomization of metals and analytes at nanoscale. The phenomenon involves formation of highly-localized nanoscale leakage channels in the oxide layer of a metal-oxide-semiconductor (MOS) structure under pulsed drive, ballistic transport of injected electrons in the nanoscale void channels, impact ionization of metal atoms, and explosive atomization of metal...
A solid-state impact-ionization multiplier (SIM) was designed to amplify signals from arbitrary current sources through impact ionization. A primary application is amplification of signals produced by photodiodes. Photodiodes made from any semiconductor can be wired directly to the SIM's injection node. Planar versions of the SIM suffer from nonideal impact ionization efficiency as a result of injected...
Summary form only given. By positively biasing an electrode immersed into low-temperature plasma up to a certain threshold value, a complex space charge structure appears in front of it, in form of a luminous quasi-spherical plasma body. This structure was sometimes called anode glow, ball of fire or fireball. Experimental investigation shown that such a structure consists of a positive nucleus (ion-enriched...
This paper reports on experimental investigation of the multiple fireballs dynamics in low-temperature argon plasma. Very complex oscillations of the current collected by the electrode, as well as of the plasma potential were recorded, in connection with this dynamics. In certain experimental conditions these oscillations were observed to become more and more complex at the increasing of the potential...
Experimental results concerning the formation of spatial and spatio-temporal patterns in low-temperature discharge plasmas are presented. These structures appear as single or multiple luminous structures attached to the anode surface, or electrode-free in the case of radio-frequency or microwave plasmas. Probe measurements revealed that a double layer exists at the edge of each structure, controlling...
