Surface acoustic waves in semi-insulating Fe-doped GaN films grown by hydride vapor phase epitaxy [PDF]

open access: yes, 2014
The propagation properties of surface acoustic waves (SAWs) in semi-insulating Fe-doped GaN films grown on sapphire substrates by hydride vapor phase epitaxy are investigated.

Growth‐Pathway‐Controlled van der Waals Epitaxy of Phase‐Selective Tin Sulfides

open access: yesAdvanced Science, EarlyView.
Growth‐pathway‐controlled van der Waals epitaxy enables deterministic phase selection and strain engineering in tin sulfide/WSe2 heterostructures. Direct growth of SnS induces substrate‐mediated strain and phase evolution, whereas sequential growth through an SnS2 buffer suppresses strain transfer and stabilizes pristine α‐SnS, revealing a versatile ...

Nuclear Spin‐Free 70Ge/28Si70Ge Quantum Well Heterostructures Grown on Industrial SiGe‐Buffered Wafers

open access: yesAdvanced Science
The coherence of hole spin qubits in germanium planar heterostructures is limited by the hyperfine coupling to the nuclear spin bath due to 29Si and 73Ge isotopes.

Luminescence properties of ZnSe films grown by hot wall epitaxy [PDF]

open access: yes, 1997
The photoluminescence (PL) properties of ZnSe films grown by hot wall epitaxy are reported. The PL spectra show clear neutral donor-bound exciton peak; donor acceptor pair (DAP) peak, conduction band to acceptor (CA) peak, and their phonon replicas until

Oxygen‐Assisted MOCVD Growth of Monolayer PtSe2 Films With Bandgap Opening for Semiconducting FET Channels

open access: yesAdvanced Science, EarlyView.
Monolayer PtSe2 films are successfully grown via optimized MOCVD, achieving uniform coverage over a 1.5 cm × 1.5 cm area. Oxygen‐assisted growth effectively removes carbon impurities, ensuring high film quality. Array‐level FETs based on monolayer PtSe2 channels demonstrate low off‐current and high ION/IOFF ratios, highlighting the potential of PtSe2 ...

TEM study of dislocations in ZnTe/GaAs heterostructure grown by hot-wall epitaxy [PDF]

open access: yes, 1999
A ZnTe layer grown on GaAs substrate by hot-wall epitaxy (HWE) was studied using transmission electron microscopy (TEM). For a (110) cross-sectional specimen, its (001) ZnTe/GaAs interface was analysed by large angle stereo-projection (LASP) and high ...

Extrinsic and Intrinsic Charge Transfer at Interfaces of Membrane‐Based Oxide Heterostructures

open access: yesAdvanced Electronic Materials, EarlyView.
Freestanding oxides have emerged as a new opportunity to tailor oxides outside of the typical epitaxial constraints. We present the fabrication of TiO2‐terminated SrTiO3 membranes via direct growth control. We demonstrate competing ionic and electronic charge transfer in LaAlO3/SrTiO3 bilayers using near ambient pressure XPS.

Uranium Doped Gallium Nitride Epitaxial Thin Films

open access: yesAdvanced Electronic Materials
Gallium nitride (GaN) is near ubiquitous in modern day technologies, forming the backbone of solid‐state lighting and high‐power electronics. Engineering the physical properties of GaN has been investigated to some degree by the incorporation or doping ...

Single Layer Growth of Strained Epitaxy at Low Temperature [PDF]

open access: yes, 2003
Contacting mode atomic force microscopy (AFM) is used to measure the In0.asGao.65As/GaAs epilayer grown at low temperature (460°C). Unlike the normal layer-by-layer growth (FvdM mode) or self-organized islands growth (SK mode) ,samples grown under 460 C ...

InGaP/GaAs/InGaAs Multijunction Flexible Photovoltaics With Chemical Robustness and Radiation Hardness for Unassisted Electrocatalysis and Space Applications

open access: yesAdvanced Energy Materials, EarlyView.
A flexible InGaP/GaAs/InGaAs triple‐junction platform encapsulated with ultrathin glass enables unassisted electrocatalysis and space applications by providing robust protection against chemically aggressive and radiation‐rich environments. This work establishes a unified III–V multijunction photovoltaic platform that bridges space photovoltaics and ...
