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…
Thermal conductivity measurements of sub-surface buried substrates by steady-state thermoreflectance
Md Shafkat Bin Hoque, Yee Rui Koh, Kiumars Aryana +10
Measuring the thermal conductivity of sub-surface buried substrates are of significant practical interests. However, this remains challenging with traditional pump-probe spectrosco…
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…
