    Abstract: Methods for magnetically enhanced physical vapor deposition are disclosed. The methods include providing a magnetically enhanced vapor deposition device defining a vapor deposition chamber, having a magnetic field source proximate a magnetron target that is positioned within the vapor deposition chamber and coupled to a power source, and having a substrate holder positioned within the vapor deposition chamber, placing a substrate in the substrate holder, activating the magnetic field source to provide a magnetic field that controls a charged particle flux within the physical vapor deposition chamber, and activating the power source thereby depositing a few-layer film of the material comprising the magnetron target onto the substrate. The few-layer film may be a transition metal dichalcogenide, such as MoS2.
