Abstract

Samples of p-type polysilicon on dielectric substrates were investigated in the temperature range of 4.2–300 K and magnetic fields up to 14 T, as well as the effect of mechanical strain on their resistance. It was shown that lightly doped, non-recrystallized poly-Si resistors (2.4·1018 cm–3) can be recommended as highly sensitive thermoresistors. For piezoresistive sensors of mechanical quantities, heavily doped, laser-recrystallized poly-Si resistors (~1.7·1020 cm–3) are recommended. These resistors also demonstrate the highest stability under strong magnetic fields.
