▼ Conducting high-temperature Hall effect measurements of various semiconductors and metals allows one to determine information regarding the carrier concentration, carrier type, and resistivity of a sample as it varies with temperature. This has an especially interesting application for military purposes and within the automotive and aerospace industries. Currently, the structural design of vehicles and industrial apparatuses is severely restricted by the limited understanding of the properties of semiconductors at high temperatures. In order to test these properties an apparatus capable of housing a conducting or semiconducting thin film sample and withstanding 1100°C with a magnetic field acting perpendicular to the direction of the flow of charge has been designed and constructed. By understanding the more fundamental characteristics of these thin films at high temperature, it may be possible to make improvements on already existing electrical components, or develop new applications entirely.
