Development and performance test of variable temperature Hall effect experiment instrument
Using semiconductor thermoelectric chips with excellent performance,an experimental in-strument for Hall effect at variable temperature is built,which can measure the Hall effect related data of N-type Hall module at variable temperature(253K～413K).Furthermore,the relationship between Hall coefficient RH(T),conductivity σ(T)and Hall mobility μH(T)and temperature is explored.The instrument can stably heat up and cool down,and does not need liquid nitrogen,which not only ex-pands the experimental content but also ensures the safety of the experiment.The experimental instru-ments are modular,and different universities can introduce different experimental contents according to the actual situation,and the cost of experimental instruments is controllable.
