Properties of Film Pickups of Hall Emf and Their Application to Measuring Magnetic Fluxes

摘要

Work was carried on in the creation of a new type of pickups of emf on the Hall principle on the basis of thin polycrystallic layers of selenide and telluride of mercury. The properties of semiconductor substances in thin layers ordinary are distinguished very much from the properties of solid specimens. Particularly, the mobility of the carriers of the electric current in films as a rule is considerably lower than in single crystals and Hall's effect is insignificantly small. As a result of the experiments conducted, technology was created permitting the obtainment of thin layers of HgSe - HgTe with a high figure for the mobile carriers of electric current. The thin film were applied to insulating mica bases by the method of thermal vaporization in a vacuum.
