Low-resistivity bulk silicon prepared by hot-pressing boron- and phosphorus-hyperdoped silicon nanocrystals

Abstract: Technologically important low-resistivity bulk Si has been usually produced by the traditional Czochralski growth method. We now explore a novel method to obtain low-resistivity bulk Si by hot-pressing B- and P-hyperdoped Si nanocrystals (NCs). In this work bulk Si with the resistivity as low as ∼ 0.8 (40) mΩ•cm has been produced by hot pressing P (B)-hyperdoped Si NCs. The dopant type is found to make a difference for the sintering of Si NCs during the hot pressing. Bulk Si hot-pressed from P-hyperdoped Si NC… Show more

“…Among all kinds of semiconductor nanocrystals (NCs), silicon (Si) NCs hold great promise for widespread applications in various fi elds such as optoelectronics, [1][2][3][4] photovoltaics, [5][6][7][8] electronics, [9][10][11] energy storage [ 12,13 ] and bioimaging. [ 14,15 ] This is largely due to the nontoxicity and abundance of Si and the compatibility of Si-NC technology with well-established bulkSi technology.…”
