Turning Low-Nanoscale Intrinsic Silicon Highly Electron-Conductive by SiO2 Coating

Summary: The study shows that impurity doping in silicon nanowells can be adjusted by nanoscale electronic structure shifts induced by anions at surfaces (NESSIAS), enhancing electron conductivity. This finding deviates from traditional understanding, but is validated through comparison with experimental data and theoretical calculations, showing that other group IV semiconductors also respond similarly to the effect. Adequate nanowire cross-sections can be predicted through crystallographic analysis, laying the foundation for the development of undoped ultrasmall silicon electronic devices with significantly reduced gate lengths.
