Position-controlled remote epitaxy of ZnO for mass-transfer of as-deployed semiconductor microarrays

open access: yesAPL Materials, 2021
We report the site-selective remote epitaxial growth of mechanically transferable ZnO microrod (MR) and microdisk (MD) arrays via hydrothermal growth. To designate the growth sites, a hole-patterned poly(methyl methacrylate) mask layer is formed on the ...

Defect seeded remote epitaxy of GaAs films on graphene

open access: yesNanotechnology, 2022
Abstract Remote epitaxy is an emerging materials synthesis technique which employs a 2D interface layer, often graphene, to enable the epitaxial deposition of low defect single crystal films while restricting bonding between the growth layer and the underlying substrate.

Excess electron screening of remote donors and mobility in modern GaAs/AlGaAs herostructures [PDF]

open access: yes, 2018
In modern GaAs/Al$_x$Ga$_{1-x}$As heterostructures with record high mobilities, a two-dimensional electron gas (2DEG) in a quantum well is provided by two remote donor $\delta$-layers placed on both sides of the well.

High speed InAs electron avalanche photodiodes overcome the conventional gain-bandwidth product limit [PDF]

open access: yes, 2011
High bandwidth, uncooled, Indium Arsenide (InAs) electron avalanche photodiodes (e-APDs) with unique and highly desirable characteristics are reported. The e-APDs exhibit a 3dB bandwidth of 3.5 GHz which, unlike that of conventional APDs, is shown not to

Extending device performance in photonic devices using piezoelectric properties [PDF]

open access: yes, 2013
This study focuses on the influence of epi-layer strain and piezoelectric effects in asymmetric GaInAs/GaAlAs action regions that potentially lead to intra-cavity frequency mixing. The theoretical limits for conduction and valence band offsets in lattice-

Magnetoresistance Induced by Rare Strong Scatterers in a High Mobility 2DEG [PDF]

open access: yes, 2014
We observe a strong negative magnetoresistance at non-quantizing magnetic fields in a high-mobility two-dimensional electron gas (2DEG). This strong negative magnetoresistance consists of a narrow peak around zero magnetic field and a huge ...
