Small electrical heating elements have been lithographically fabricated onto the culets of 'designer' diamond anvils for the purpose of performing high-pressure and high-temperature experiments on metals. The thin-film geometry of the heating elements makes them very resistant to plastic deformation during high pressure loading, and their small cross-sectional area enables them to be electrically heated to very high temperatures with relatively modest currents ({approx}1 Amp). The technique also offers excellent control and temporal stability of the sample temperature. Test experiments on gold samples have been performed for pressures up to 21 GPa and temperatures of nearly 2000K.
