Claim 0:
1. A method for dispensing an elemental-alkali metal, the method comprising:
providing a highly-oriented pyrolytic graphite (“HOPG”) volume intercalated with elemental rubidium (“Rb”), the HOPG volume being positioned within a vacuum chamber at a vacuum pressure below 1.3×10−5 Torr;
heating the HOPG volume such that the HOPG volume emits the Rb at a partial pressure between 1×10−11 and 1×10−6 Torr, wherein the HOPG volume is intercalated with elemental Rb by vacuum baking the HOPG volume while the HOPB volume is positioned proximate the elemental Rb until the HOPG volume has increased in size.
