 | Stringfellow, Gerald B.; Rieth, Loren W. | Effects of Br and Cl on organometallic vapor phase epitaxial growth and ordering in GaInP | CuPt ordering in GaInP has significant effects on the electrical and optical properties. In fact, band gap reductions as large as 160 meV are potentially useful for devices. Thus, control of ordering is important. This has led to the investigation of surfactants that affect the surface processes d... | Band gap reductions; Surfactants; Surface processes | 2004 |

 | Stringfellow, Gerald B. | Effects of low surfactant Sb coverage on Zn and C incorporation in GaP | The use of surfactants during the vapor phase growth of III-V materials to control fundamental characteristics of epitaxial layers is becoming increasingly important. We have investigated the remarkable effects of Sb, from triethylantimony (TESb) Pyrolysis, on the Zn doping during the organometallic... | Surfactants; Organometallic vapor phase epitaxy; Gallium phosphide | 2007 |

 | Stringfellow, Gerald B. | Influence of Sb, Bi, Tl, and B on the incorporation of N in GaAs | GaAs:N is an interesting material for many devices due to its unique compositional variation of band gap. Small amounts of N lead to a strong decrease in band gap energy as well as lattice constant. The further addition of In or Sb leads to quaternary alloys with band gap energies below 1.4 eV latti... | Antimony; Gallium Arsenide; Nitrogen | 2002 |

 | Stringfellow, Gerald B. | Kinetics of Te doping in disordering GaInP grown by organometallic vapor phase epitaxy | Te-doped GaInP epitaxial layers were grown by organometallic vapor phase epitaxy in an effort to clarify the Te disordering mechanism. CuPt ordered GaInP is produced under normal growth conditions. The addition of Te has been reported to induce disorder. One suggested mechanism for disordering GaInP... | Crystal growth; Epitaxy; Dynamics | 2001 |

 | Stringfellow, Gerald B. | Nitrogen surfactant effects in GaInP | The addition of surfactant nitrogen during the growth of GaInP on 001 GaAs substrates produces significant and interesting changes in the optical and morphological properties of GaInP. In particular, multiple peaks are seen in the low temperature photoluminescence (PL) spectra of GaInP/GaInP:N he... | Surfactant nitrogen; Microscopy; Crystals | 2004 |

 | Stringfellow, Gerald B. | Spectroscopic study of surfactant enhanced organometallic vapor phase epitaxy growth of GaInP | Samplen s of GaxIn1-xP grown by organometallic vapor phase epitaxy on (001) GaAs substrates by addition of TESb demonstrating a lateral superlattice compositional modulation (CM) have been studied by low temperature polarized photoluminescence (PL), power dependent PL, and photoluminescence excitati... | Organometallic vapor; Photoluminescence excitation; Spectroscopy | 2001 |

 | Stringfellow, Gerald B. | Use of Nitrogen to disorder GaInP | Significant changes in microstructure, surface structure, and alloy composition have been observed in GaInP with the addition of nitrogen. These effects occur due to surface changes induced by small concentrations of nitrogen. Transmission electron microscopy and photoluminescence experiments indica... | Nitrogen; Alloys; Transmission | 2004 |
