Objective: Investigating electrical conduction mechanisms in doped germanium with the Hall effect The Hall effect occurs in electrically conductive materials located in a magnetic field B. The Hall voltage’s sign changes depending ... 更多

Objective: Record the characteristic curve for a photoresistor Photoconductivity utilises absorption of light by means of the inherent photoelectric effect in a semiconductor to create electron-hole pairs. One specific semiconductor ... 更多

Objective: Record characteristics for various thermocouples and determine their sensitivity If the ends of a metal wire are at different temperatures, since the thermally generated motions of the electrons have different velocities, thermal ... 更多
