Abstract:
1. A method for doping a silicon substrate, the method comprising: depositing a dopant ink comprising doped silicon-based nanoparticles onto the silicon substrate to form a doped deposit, wherein the doped silicon based nanoparticles comprise doped silicon nanoparticles and/or doped silica nanoparticles; depositing a non-doped inorganic capping layer over the doped deposit on the silicon substrate; and heating the silicon substrate having the doped deposit with the capping layer to drive dopant atoms into the silicon substrate, the heating forming a structure having the capping layer disposed over the doped deposit, wherein the doped deposit having a capping layer on the silicon substrate has a sheet resistance of no more than about 60 ohms per square after the heating.
