    Abstract: Methods include arranging a substrate in a vacuum chamber of a charged particle beam microscope, wherein the substrate is held at a cryogenic temperature, and depositing on the substrate at the cryogenic temperature a condensate precursor that is stored in a crucible, wherein the deposited condensate precursor forms a deposition layer on the substrate. An apparatus include a vacuum chamber configured to support a substrate, a condensate precursor system coupled to the vacuum chamber, wherein a vacuum pump is configured to draw a vacuum on a storage reservoir to reduce a vapor pressure build-up of a one or more volatile contaminants in the storage reservoir and thereby reduce a deposition of the one or more contaminants on the substrate during the condensing of the condensate precursor on the substrate. A condensate precursor can comprise a transition metal center comprising hafnium or osmium. Related deposition and cap layers are disclosed.
