ABSTRACT
Ohmic contacts to perylene molecular crystals were successfully formed at bromine-doped p-type crystal/platinum junctions and sodium-doped n-type crystal/aluminum junctions to enable hole and electron injection, respectively. Charge-carrier doping of the organic semiconductor surface that was in direct contact with the metal electrodes was revealed as being a requirement for fabricating organic/metal junctions that were ohmic in character. The fabrication of ohmic contacts would be applicable to carrier injection in organic electroluminescent devices and carrier extraction from organic solar cells.

    The resistance of alloyed In-GaN ohmic contact is studied experimentally. In the temperature range 180–320 K, the resistance per unit area increases with temperature, which is typical of metallic conduction and disagrees with current flow mechanisms associated with thermionic,...

    We report on a promising Ni (5 nm)/Al-doped ZnO (AZO) (450 nm) metallization scheme for low resistance and transparent ohmic contacts to p-GaN (5 × 10[SUP17]cm[SUP-3]). It is shown that the as-deposited Ni/AZO contact shows a nonohmic characteristic due to the insulating nature of the...

    The authors used depth-resolved cathodoluminescence spectroscopy and current-voltage measurements to probe the temperature-dependent formation of native point defects and reaction layers at metal-ZnO interfaces and their effect on transport properties. These results identify characteristic...

    A mechanism of current flow in an alloyed ohmic In contact to low-doped gallium arsenide ( n = 4 × 1015 cm−3) is studied. From the temperature dependence of the contact resistance per unit surface area, it is found that the basic mechanism of current flow is thermionic emission through...

    Ohmic contacts to GaAs/AlGaAs core/shell nanowires are prepared by using a Ni/AuGe/Ni/Au layer system. In contrast to Ohmic contacts to planar GaAs/AlGaAs layer systems here, relatively low alloying temperatures are used in cylindrical geometry. Lowest resistances are found for annealing...

    The contact mechanism and design principles for nonalloyed ohmic contacts are investigated. Illustrative studies of various contacts show wide validity of the design principles. Experimental measurement suggests that reactive ion etching (RIE) of the n-GaN surface creates extra electrons. There...

    Based on the study of the temperature dependence of resistance of the In- n-GaN alloyed ohmic contacts, it is found that the mechanism of current flow in them substantially depends on the concentration N of uncompensated donors in GaN. At N = 5 × 1016 − 1 × 1018 cm−3, current...
