A Kelvinox 400 dilution refrigerator with the ability to load samples onto the mixing chamber from the bottom of the cryostat has been combined with an ultrahigh-vacuum (UHV) deposition chamber equipped with molecular beam sources. The liquid helium cooled sample transfer mechanism is used in a manner that allows films to be grown on substrates which are kept at temperatures of order 8K with ch...

Intelligent Refrigerator with Monitoring Capability through Internet

In conventional or standard refrigerator there is no system of automatically monitoring the materials or food items and also it will not replace immediately. An intelligent refrigerator is one which possesses self monitoring capability of food item or material with minimal or no human intervention. Such a product should have the capability of automatically detecting and alerting the consumer of...

Ultrahigh vacuum glancing angle deposition system for thin films with controlled three-dimensional nanoscale structure

An ultrahigh vacuum apparatus for the deposition of thin films with controlled three-dimensional nanometer-scale structure is described. Our system allows an alternate, faster, cheaper way of obtaining nanoscale structured thin films when compared to traditional procedures of patterning and etching. It also allows creation of porous structures that are unattainable with known techniques. The un...

Automatic kelvin probe compatible with ultrahigh vacuum

This article describes a new type of in situ ultrahigh-vacuum compatible kelvin probe based on a voice-coil driving mechanism. This design exhibits several advantages over conventional mechanical feed-through and (in situ) piezoelectric devices in regard to the possibility of multiple probe geometry, flexibility of probe geometry, amplitude of oscillation, and pure paranel vibration. Automatic ...
