Удельное сопротивление германия, измеренное линейным четырехточечным датчиком постоянного тока - критерий

The single crystal germanium is n type at room temperature, and the resistivity shows non-single dependence on temperature. When conduction type transits from n type to p type, the bulk germanium resistivity is in maximum, and the carrier mobility is declining. With the increasing of dopant concentration, the transition [...]
