SOME semiconductors have comparatively low resistivity, and this is due to their containing electrically active impurities with energy-levels near a band edge. Others have very high resistivity and this is due to their containing a predominance of impurities with levels far from the band edges, that is, far compared with the thermal energy kT. These latter materials are often referred to as insulators, but since they can carry electronic currents we prefer to introduce the term ‘semi-insulator… 

Properties of Semi‐Insulating GaAs

Most samples of GaAs show properties similar to those of germanium and silicon, but it is possible to prepare GaAs with a resistivity at room temperature greater than 106 ohm‐cm, and the electrical

Space-Charge Currents in Gallium Arsenide

Mott and Gurney1 pointed out that an insulator should be able to carry an electronic current if electrons were injected into it by a suitable contact. Such currents were observed experimentally by

Energy-Level Model for High-Resistivity Gallium Arsenide

ALTHOUGH gallium arsenide is usually prepared with low resistivities (<1 ohm-cm.), it has also been prepared for several years with very high resistivities (> 106 ohm-cm.). This latter material can

Space Charge Limited Currents in Cadmium Sulphide Crystals

In order to test whether Lampert's theory (1956) of one carrier space-charge-limited currents can be applied to cadmium sulphide it is necessary to ensure that the electrical contacts to the crystals

Oxygen in gallium arsenide

The evolution of the deep level transient spectroscopy spectrum associated with the EL2 defect in epitaxial as well as bulk GaAs materials when they are contaminated by oxygen has been examined in

Tantalum doping and high resistivity in aluminium antimonide

Aluminium antimonide crystals grown by the Czochralski method from melts doped with tantalum are found to have a lower residual acceptor concentration and increased free hole mobility than crystals
