The growth and performance of vapor phase epitaxial W E ) III-V materials and devices for lightdtting diode (LED) and display applications are reviewed. Because of the commercial importance of the GaAsP ternary alloys and Gap, this paper is pri-The 111-V material systems with potential for LED apd Y mncerned with these materials. With the addition of nitrogen plications have recently been reviewed by Archer [ 9 ] . These fabricated using GaAsP and GaP. The W E materials growth tech-doping high-performance * yellow, anddevicesbe include the direct materials: GaAsl,P, (x
