What Has Government Done to Our Money? What Has Government Done to Our Money? What Has Government Done to Our Money? is a 1963 book by Murray N. Rothbard that details the history of money, from early barter systems, to the gold standard, to present day systems of paper money. Rothbard explains how money was originally developed, and why gold was chosen as the preferred commodity to use as money. The essay, "What Has Government Done to Our Money?" was written by Rothbard as an objective historical account with a provocative title. In contrast, "The Case for a 100 Percent Gold Dollar" was an essay with an
Ultra-high-purity steam for oxidation and annealing and is both less expensive and safer. An effective passivation of the rear surface of industrial solar cells is a prerequisite to considerably improve the conversion efficiency. An excellent level of surface passivation on lowly doped p-type surfaces is provided by thermal grown silicon oxides. However, dry thermal oxidation processes require relatively high temperatures (>1000 °C) and, due to the low growth rate, long process times. To decrease both oxidation temperature and process time the dry oxidation process can be replaced by a wet oxidation followed by nitrogen annealing. Best cell performance requires a forming gas anneal after firing. Ultra-high-purity
