Abstract

1512322 Light emitting diodes SONY CORP 21 Jan 1976 [29 Jan 1975] 2332/76 Heading H1K A green light emitting diode comprises, on a GaP substrate 1, e.g. of N-type, an N-containing epitaxial GaP layer 2 including a first N-type portion 2n adjacent the substrate 1 and a second P-type portion 2p on the portion 2n. The doner concentration in the portion 2n is 1 Î 10<17>-2 x 10<18> atoms/cm.<3> and the acceptor concentration gradient in the portion 2p adjacent the PN-junction J is not less than 7 x 10<20> atoms/cm.<3> per cm. The substrate 1 is preferably doped with S or Te, the portion 2n with N and S or Te and the portion 2p with Zn and N. An apparatus and method for the liquid phase epitaxial deposition of such a diode is disclosed.
