Abstract: A PN JUNCTION IS FORMED IN A SOLUTION GROWN EPITAXIAL LAYER CONSISTING OF A MIXED III-V COMPOUND SEMICONDUCTIVE MATERIAL BY UTILIZING A SINGLE AMPHOTERIC CONDUCTIVITY MODIFIER IN THE SOLUTION, AND VARYING THE TEMPERATURE OF THE SOLUTION DURING THE DEPOSITION OF THE EPITAXIAL LAYER. THE SEMICONDUCTIVE MATERIAL HAS THE COMPOSITION BAALBGACINDNEPFASGSBH, WHEREIN EACH OF SUBSCRIPTS, A, B, C, D, E, F, G, H RANGES FROM 0 TO 1, AND A+B+C+D=1, AND E+F+G+H=1. THE AMPHOTERIC CONDUCTIVITY MODIFIER IS SILICON OR GFERMANIUM, AND THE ADDITION OF THE AMPHOTERIC MODIFIER TO THE SOLUTION SHORTLY BEFORE THE DEPOSITION OF THE EPITAXIAL LAYER IS ESPECIALLY EFFICACIOUS. ALSO DESCRIBED IS THE FABRICATION OF AN IMPROVED ELECTROLUMINESCENT DIODE FROM A SUB-CLASS OF THE MIXED III-V COMPOUND MATERIALS COMPRISING TWO MEMBERS OF THE GROUP CONSISTING OF BORON, ALULMINUM, GALLIUM AND INDIUM, AND ONE MEMBER OF THE GROUP CONSISTING OF NITROGEN, PHOSPHORUS, ARSENIC AND ANTIMONY.

Abstract: AN EPITAXIAL LAYER OF SINGLE CRYSTALLINE GALLIUM ARSENIDE OR ALUMINUM GALLIUM ARSENIDE HAVING A LOW CONCENTRATION OF ALUMINUM IS DEPOSITED ON A BODY OF SINGLE CRYSTALLINE SEMICONDUCTOR MATERIAL BY LIQUID PHASE EPITAXY. AN ADDITIONAL LAYER OF SINGLE CRYSTALLINE ALUMINUM GALLIUM ARSENIDE HAVING A RELATIVELY HIGH CONCENTRATION OF ALUMINUM IS DEPOSITED BY LIQUID PHASE EPITAXY ON THE EPITAXIAL LAYER. THE ADDITIONAL LAYER IS THEN COMPLETELY ETCHED AWAY BY AN ETCHANT WHICH DOES NOT ATTACK THE MATERIAL OF THE EPITAXIAL LAYER, SUCH AS BOILING HYDROCHLORIC ACID, TO EXPOSE THE ENTIRE SURFACE OF THE EPITAXIAL LAYER AND PROVIDE THE EPITAXIAL LAYER WITH A SMOOTH, FLAT SURFACE.

Abstract: A transmission photocathode device of the negative-electronaffinity type is disclosed. The device comprises epitaxially grown P type semiconductor layers and an alkali metal or alkali metal-oxygen work-function-reducing activation layer. Also disclosed is a novel method for making a negative-electronaffinity transmission photocathode device. The method enables a photocathode device to be made by the serial epitaxial growth of p type layers of a II-VI or III-V semiconductor on a semiconductor substrate. The method provides for a virtually perfect lattice match between the semiconductor layers thereby increasing the efficiency of the photocathode by eliminating lattice defects which would otherwise exist at the interface between the transmitting material and the absorbing material.

Abstract: An electron emitter comprising a body of a semiconductor material which is adapted to generate light therein when properly biased but which is a poor absorber of the generated light. On a surface of the body is a thin region of a semiconductor material which is a good absorber of the generated light and which has an index of refraction which substantially matches the index of refraction of the material of the body. The thin semiconductor material region is adapted to absorb the light from the body and convert the light into free electrons. On the surface of the semiconductor material layer is a thin film of an electropositive work function reducing material which is adapted to emit the electrons formed in the semiconductor material layer.

Abstract: A diode laser is improved in order to produce an output in a single longitudinal mode. The laser has a rectangular body with two regions of differing conductivity type material. Extending from one surface of the rectangular body and into one of the regions of differing conductivity material is a third region. Although the third region is composed of the same general conductivity type material as the region into which it extends, it is more highly doped with conductivity modifiers (more conductive). This third region extends along one surface between the ends of the body and is spaced from the sides of the body. An electrical contact stripe is positioned on the one surface so that a portion of its width overlaps a portion of the width of the third region.

Abstract: A single crystalline body of three conductivity regions. The center conductivity region forms junctions with the other two regions that diverge from each other as the junctions extend toward the emitting surface of the light emitting diode. The divergent junction structure improves the waveguiding of the generated light toward the emitting edge.
