Hall Effect detector

Any residual material left in the shuttle is blanketed by a slow flow of dry nitrogen gas to prevent fouling of the shuttle between uses. Pneumatic cylinders, driven from solenoid valves that are controlled by a power- and event-controller, provide the shuttle motion, and position is confirmed by Hall Effect detectors on the pneumatic cyhnders and monitored by the power and event controller. 

Antimony alloys have many commercial applications. The metal makes its alloys hard and stiff and imparts resistance to corrosion. Such alloys are used in battery grids and parts, tank linings, pipes and pumps. The lead plates in the lead storage batteries constitute 94% lead and 6% antimony. Babbit metal, an alloy of antimony, tin, and copper is used to make antifriction machine bearings. Alloys made from very high purity grade antimony with indium, gallium and bismuth are used as infrared detectors, diodes, hall effect devices and thermoelectric coolers. 

Indium antimonide is used in semiconductor and Hall effect devices, and infrared detectors. 

IR spectra were taken at room temperature (300 K) and liquid-helium temperatures (5-15 K), using a Bomem DAS Fourier transform infrared (FTIR) spectrometer and an InSb detector. For the low-temperature measurements, a Janis continuous-flow liquid-helium cryostat with wedged, IR-transparent windows was utilized. Hall-effect measurements, in the Van der Pauw geometry, were performed at room temperature using a system from MMR Technologies. Wires were attached to the ZnO using silver paint, which provided adequate Ohmic contacts for the electron concentrations (10 cm ) in these samples. 

Important intermetaUics are the III V semiconductors for infrared detectors AlSb (band gap, 2.2 eV), GaSb (band gap, 0.7 eV), and InSb (band gap, 0.2eV), which can be used as diodes and Hall effect devices. Precursors of these semiconductors are products obtained by reactions of Sb(SiR3)3 and alkyl derivatives of group 13 metals, for example, Lewis acid base adducts R3M Sb(SiR3)3 (M = AI, Ga, In R = alkyl) or heterocycles [R2MSb(SiMe3)2] (n = 2, 3). - ...
