Stable field-induced electron emission from a solidified liquid metal ion source
Stable field-induced electron emission is derived from a tungsten tip covered by indium which has been solidified from its liquid state during an ion emission process. By choosing different ion emission currents at the beginning of the solidification process, the final geometry of the solidified emitter can be reshaped and the characteristics of the electron emission changed. The Fowler– Nordhe...
متن کاملSupported Liquid Membrane in Metal Ion Separation: An Overview
Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...
متن کاملMg–Ga liquid metal ion source for implantation doping of GaN
A magnesium liquid metal ion source was investigated for p-type doping of GaN. The metal is an alloy composed of 33.3% Mg and 66.7% Ga. The source type is a direct heating needle source with a spring-type reservoir, which is constructed using tungsten wire and a ceramic tube. The source has been tested and characterized in a NanoFab 150 focused ion beam ~FIB! system. A typical source lifetime w...
متن کاملANGULAR RESOLVED ENERGY ANALYSIS OF 69Ga+ IONS FROM A GALLIUM LIQUID METAL ION SOURCE
An analysis system has been designed and built to characterise liquid metal ion source beams. Both mass and angular resolved energy distribution measurements can be made, from which both FWHM energy spreads and energy deficits can be obtained. This paper briefly describes the system and presents and discusses the first off-axis results taken with a gallium liquid metal ion source. Liquid metal ...
متن کاملAn Analytical Expression for the Current-voltage Characteristics of Capillary Type Liquid Metal Ion Sources
An analytical expression, based on space-charge considerations, is derived for the current-voltage characteristics of capillary-type liquid metal ion sources. Good agreement is found with experiment.
