Discusses the design and construction of a quasilogarithmic current-voltage converter which allows currents spanning an exceptionally broad range from 10 pA to 10 mA with a bandwidth greater than 2 kHz to be measured. Design considerations and results; Ideal use of the converter for studying local interactions in scanning tunneling microscopy.

    Two versions of a double-stage "2-2 type" apparatus have been made in which 5- or 10-mmdiam sintered diamond anvils with 2.5- or 4-mm-diam tips, respectively, are used in the second stage. The experiments show that these apparatuses are capable of attaining static pressures of over 20 GPa. The...
