From the calculation of Seebeck coefficients of both p-type and n-type, it is found that for p-type, the Seebeck coefficient is about 130 μV/K, while for n-type, the value is −110 μV/K (Fig. 9 shows the absolute value).
Web4 jun. 1998 · The etch rate of doped polycrystalline silicon films (polysilicon) was studied as a function of dopant concentration, degree of dopant activation, and dopant type, in a parallel‐plate reactor, using a CFCl 3 plasma. The significant difference in etch rate between n‐doped and p‐ or undoped polysilicon observed indicates that the electrical activity of … WebP-type and N-type multi-gate vertical thin film transistors (vertical TFTs) have been fabricated, adopting the low-temperature (T ≤ 600°C) polycrystalline silicon (polysilicon) technology. Stacked heavily-doped polysilicon source and drain are electrically isolated by an insulating barrier.
