What is the effect of temperature on hall coefficient of a lightly doped semiconductor?

hall coefficient of a lightly doped semiconductor will decrease with increase in temp as hall coefficient is inversely proportional to number density of charge carriers.


Why value of hall coefficient is negative?

The Hall coefficient has the same sign as the charge carrier. The charge carrier in a normal electric current, the electron, is negative, and as a result the Hall coefficient is negative.

What is value of hall coefficient of ge?

The Hall coefficient of germanium typically ranges from 0.003 to 0.006 m^3/C. It is a material property that characterizes the ability of a material to conduct current perpendicular to an applied magnetic field.


What is the Value of Hall coefficient of germanium?

The Hall coefficient of germanium is typically around -0.018 cm³/C. This value indicates the sign and magnitude of the charge carriers in germanium, which are primarily electrons. The negative sign indicates that the charge carriers are negatively charged electrons.

What is the significance of the coefficient of performance in the refrigeration cycle?

The coefficient of performance in the refrigeration cycle is important because it indicates how efficiently the refrigeration system can transfer heat. A higher coefficient of performance means the system is more efficient at cooling, which can lead to lower energy consumption and cost savings.
