Methods of using vapor cells may involve providing a vapor cell including a body defining a cavity within the body. At least a portion of at least one surface of the vapor cell within the cavity may include at least one pore having an average dimension of about 500 microns or less, as measured in a direction parallel to the at least one surface. A vapor pressure of a subject material within the cavity may be controlled utilizing the at least one pore by inducing an exposed surface of a subject material in a liquid state within the at least one pore to have a shape different than a shape the exposed surface of the subject material in a liquid state would have on a flat, nonporous surface.
