Investigation of the Effect of Hall, Hall Constant and Density on Conductors Silver, Copper and Tungsten
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2021, Vol 5, Issue 5
Abstract
Effect of Hall is the most applied issue in materials science. The purpose of this paper is to investigate the effect of Hall on conductive metals such as silver, copper, and tungsten. Dimensions of the copper sheet 83mm × 25mm × 20µm and dimensions of the silver sheet 25mm × 83mm × 43µm and dimensions of the tungsten sheet 82mm × 20mm × 30µm were investigated, as a result, the Hall voltage sign was positive in silver and tungsten and negative in copper. The reason for the negative sign of Hall voltage in silver and tungsten is that the hole carriers overcome the electron carriers and in copper, the electron carriers overcome the hole carriers. Due to the magnetic field of 200mT, then the Hall constant is 8× 10 3 mV TAfor silver and 6.56× 10 3 mV TAfor copper. According to the symbol, the constant of Hall in silver and tungsten are p type and for copper is n type. Also, due to the current passing through the semiconductor in the amount and changing the magnetic field for the silver and copper samples, the Hall constant is obtained 7.84× 10 3 mV TA and 7.24× 10 3 mV TA, respectively. The carrier densities are 7.89× 10 20 1 m 3 for silver and 9.06× 10 20 1 m 3 for copper obtained.
