Abstract
A new nanocomposite material with stable properties has been obtained representing a metal (indium) incorporated into a semiconducting porous silicon (por-Si) matrix. Electrical properties of the por-Si-In nanocomposite have been studied for the first time. At low temperatures (T = 1.4–4.2 K), the por-Si-In samples exhibit a positive magnetoresistance [ΔR/R(H = 0) ≈ 600%], which is related to breakage of the superconducting state of In particles in the por-Si matrix.
