Title: AlGaAs/GaAs nano-hetero-epitaxy on a patterned GaAs substrate by MBE

Abstract

An AlGaAs/GaAs resonant tunneling diode (RTD) with submicron size was fabricated on {l_brace}111{r_brace} oblique facets of GaAs with selective MBE. The method is based on the fact that a certain facet structure is formed on a patterned substrate in selective MBE because the growth rate depends strongly on the facet structure. The fabrication of a double-barrier structure was attempted on a {l_brace}111{r_brace}B facet. The current-voltage characteristics of the sample showed negative differential resistance at 77K demonstrating that we have achieved an RTD on a submicron facet.

  • Anisotropic selective epitaxy in nanoscale-patterned growth (NPG) by molecular-beam epitaxy is investigated on a 355 nm period two-dimensional array of circular holes fabricated in a 30-nm-thick SiO{sub 2} film on a GaAs(001) substrate. The hole diameter ranged from 70 to 150 nm. The small hole diameter and the very thin masking layer stimulated lateral growth over the SiO{sub 2} surface at an early stage of selective epitaxy on this patterned substrate. Lateral overgrowth associated with selective epitaxy, however, did not proceed isotropically along the circular boundary between the open substrate surface and the SiO{sub 2} mask. There was preferential growthmore » direction parallel to <111>B. This anisotropy in the selective epitaxy resulted in the formation of a nanoscale, nontapered, straight-wire-type epitaxial layer (GaAs nanowires), which had a length of up to 1.8 {mu}m for a nominal 200 nm deposition. Every GaAs nanowire had a hexagonal prismatic shape directed along <111>B and was surrounded by six (110) sidewalls. The anisotropy of selective epitaxy and faceting in NPG were affected by the profile of the SiO{sub 2} mask and are interpreted using a minimization of the total surface energy for equilibrium crystal shape.« less
  • AlGaAs/GaAs multiquantum well lasers and GaAs metal-semiconductor field-effect transistors have been monolithically integrated on a semi-insulating GaAs substrate by using molecular beam epitaxy. This integrated laser has exhibited cw operation with the low threshold current of 20 mA at room temperature. The laser/field-effect transistor (FET) characteristics, such as a linear control of laser output power by changing the FET gate voltage, have been confirmed. A conversion ratio of laser output power to FET gate voltage has been measured to be as high as 3.3 mW/V. Rise and fall times of 1 ns have been demonstrated.
  • We report on the frequency response of quantum well lasers on Si substrates grown by molecular beam epitaxy. Ridge waveguide lasers of 10 ..mu..m x 380 ..mu..m having threshold currents as low as 40 mA were used in this study. Measurements were performed up to a frequency of 4.5 GHz with a resultant modulation corner frequency of 2.5 GHz when the laser was operated about 20% above the threshold.
  • We investigated molecular beam epitaxial growth characteristics on (001) GaAs substrates with a pair of etched grooves along the <110> direction. It is found that, as the growth proceeds, the mesa width between the pair of grooves gradually decreases and that the grown mesa surface becomes slightly concave. These results offer great advantages for precisely defining the lateral width of index guided lasers during growth. A pair-groove-substrate GaAs/AlGaAs multiquantum well laser has been newly developed, which shows stable fundamental transverse mode oscillation and a high external differential quantum efficiency of 68% as well as a low threshold current of 23more » mA.« less
  • (GaAl)As/GaAs multiple quantum well channeled-substrate lasers with lateral index guiding have been made by molecular beam epitaxy. They operate stably in a single longitudinal mode.
