| Zusammenfassung: | Multicolor light emitting diode arrays can be made using a binary semiconductor substrate on which is grown a graded epitaxial region of an AB1-xCx semiconductor. Diodes emitting various light colors can selectively be formed in different regions of the gradient by etching away a portion of the graded region. Arrays of colored light emitting diodes can be made by the techniques of diffusion and selective etching of the graded material. |
