![]() | Stringfellow, Gerald B. | Photoluminescence of Shallow Acceptors in Epitaxial AlGaAs | The low-temperature (2 K) photoluminescence (PL) of AlxGa1-xAs (0<x<0.25 was studied in an effort to characterize shallow acceptors in material grown by organometallic vapor phase epitaxy and liquid phase epitaxy techniques. The dominant shallow acceptor in nominally undoped AlxGa1-xAs specimens gro... | Photoluminescence; Acceptors; Doping | 1980 |
