Assessment of the (010) -GaO Surface and Substrate Specification
Michael A. Mastro, Charles R. Eddy, Marko J. Tadjer +3
Recent breakthroughs in bulk crystal growth of the thermodynamically stable beta phase of gallium oxide (-GaO) have led to the commercialization of large-area beta-Ga$_2…
III-Nitride Nanowire Based Light Emitting Diodes on Carbon Paper
Michael A. Mastro, Travis J. Anderson, Marko J. Tadjer +4
This article presents the use of flexible carbon substrates for the growth of III-nitride nanowire light emitters. A dense packing of gallium nitride nanowires were grown on a carb…
Nickel Foam as a Substrate for III-nitride Nanowire Growth
Michael A. Mastro, Neeraj Nepal, Fritz Kub +3
This article presents the use of flexible metal foam substrates for the growth of III-nitride nanowire light emitters to tackle the inherent limitations of thin-film light emitting…
Polarization and Space Charge Limited Current in III-Nitride Heterostructure Nanowires
Michael A. Mastro, Hong-Youl Kim, Jaehui Ahn +5
An undoped AlGaN/GaN nanowire demonstrated p-type conductivity based solely on the formation of hole carriers in response to the negative polarization field at the (000-1) AlGaN/Ga…
Plasmonically-Enhanced Emission from an Inverted GaN Light Emitting Diode
Michael A. Mastro, Byung-Jae Kim, J. A. Freitas +5
Silver nanoparticles dispersed on the surface of an inverted GaN LED were found to plasmonically enhance the near-bandedge emission. The resonant surface plasmon coupling led to a…
Design of Gallium Nitride Resonant Cavity Light Emitting Diodes on Si Substrates
Michael A. Mastro, Joshua D. Caldwell, Ron T. Holm +2
A GaN resonant cavity light emitting diode was built on a GaN-AlN distributed Bragg reflector grown on a silicon substrate. The electroluminescence output increased by 2.5 times fo…
