HCS – Hall coefficient – Inorganics/semiconductors

Antimony thin film – Hall coefficient – resistivity – mobility

Thermoelectric materials and microelectronics constitute a vast and crucial research field in modern industries. With the continuous downscaling of computer chips, electronic boards, and processors to nanometer ranges, effective heat management becomes increasingly essential. Understanding the influence of heat and magnetic fields on materials, along with investigating their thermoelectric behavior, holds significant interest.

App. Nr. 02-010-001 HCS – Hall coefficient – Inorganics semiconductors

Application Number 02-010-001 HCS focuses on the measurement of the Hall coefficient, Mobility, and Resistivity of a 150 nm thick antimony (Sb) thin film sample. This research spans a temperature range from room temperature to 180°C. Antimony is commonly utilized in thermoelectric materials, often in the form of alloys (e.g., Bi1−xSbx), and is finding emerging applications in the field of microelectronics. Notably, metallic antimony’s largest applications lie in lead–acid batteries, particularly in the form of lead antimony plates.

Examining the provided plot, the blue curve illustrates the resistivity, which increases with temperature—a characteristic behavior for a metallic sample. The orange curve represents the charge carrier mobility, demonstrating a decrease as resistivity increases. The green curve denotes the Hall coefficient, describing the sensitivity of charge carriers to external magnetic influences.
