Plasma-Ionizedgas Plasma/Ionized Gas Impurity Sensor The Impurity Filterscope for measuring visible light emission from plasmas and ionized gases The filterscope is a diagnostic for monitoring visible light emission from plasmas and other ionized gases. Light from a plasma is conducted to the filterscope via optical fibers. This light is split into multiple paths, and optical bandpass filters in…

Sensingindividualcarbon Contour plot of FE current (in nA) from an isolated VACNC, measured during a raster scan of the 2- m- diam probe at a height of 10 m above the substrate surface and biased at 300 V. The probe was scanned in discrete steps of 2 m with a current measurement taken after each step. Sensing Individual Carbon Nanotube Emissions Probe for mapping field emission from individua…

Atomichydrogensensor Atomic Hydrogen Sensor Low-cost sensor for measuring the atomic fraction in highly dissociated hydrogen Atomic hydrogen is a very important constituent for a number of important processes. These include the removal of oxides from GaAs, the effective cleaning of oxides and hydrocarbons from Ge and Si surfaces, the chemical passivation and surface reconstruction of cleaned Si …
