Chemical doping is a technique in the semiconductor field where a foreign substance is ‘doped’ onto the wafer to draw electron density and therefore drive current. A new technique has just recently (published two days ago) shown promise for a 2D titanium disulfide (TiSe2) surface. By applying external electric and magnetic fields, superconductivity was obtained. This is better than chemical doping because a) superconductive materials have zero electrical resistance, which means perfect conducting and b) chemical doping involves an irreversible chemical reaction. Superconductors are usually found in low temperature applications, but with the applied electric and magnetic fields, higher temperature applications can be considered, leading to changes in everything from surgery to Maglevs.
