Reducing the Radiation Conductivity of Germanium as a Result of Ionic Bombardment and the Possibility of Its Practical Utilization,
Abstract
The radiation-caused conductance in Ge occurs when the Ge surface is bombarded by fast or slow (a few hundred ev) ions. If the bombardment is continued, the additional conductance falls off. Thus, a Ge crystal with an additional conductance caused by a 100-10,000 ev ion bombardment exhibits an abrupt reduction of its conductance on subsequent bombardment by protons, given molecular ions, He-, Li-, Na-, or Cs-ions. The reduction of the radiation conductance of Ge induced by given ions at 5 kev and at 2 kev is illustrated in a figure where the ratio of additional-conductance given current to primary ion current I is plotted against the number of ions hitting 1 sq. cm. of specimen surface. The above phenomenon can be used for measuring ion- or neutral-particle-beam cross-section, density distribution, etc.; also, it can be employed for recording ions and atoms bombarding walls and electrodes, of electron and ion devices and the like.
