Transport and Interfacial Injection of d-Band Hot Holes Control Plasmonic Chemistry
Giulia Tagliabue, Fateme Kiani Shahvandi, Alan Richard Bowman, Omer Can Karaman, Milad Sabzehparvar
Harnessing nonequilibrium hot carriers from plasmonic metal nanostructures constitutes a vibrant research field with the potential to control photochemical reactions, particularly for solar fuel generation. However, a comprehensive understanding of the int ...
AMER CHEMICAL SOC2023Monolithic InSb nanostructure photodetectors on Si using rapid melt growth
Anna Fontcuberta i Morral, Nicholas Paul Morgan, Heera Menon
Monolithic integration of InSb on Si could be a key enabler for future electronic and optoelectronic applications. In this work, we report the fabrication of InSb metal-semiconductor-metal photodetectors directly on Si using a CMOS-compatible process known ...
ROYAL SOC CHEMISTRY2023Momentum-Space Imaging of Ultra-Thin Electron Liquids in δ-Doped Silicon
Two-dimensional dopant layers (δ-layers) in semiconductors provide the high-mobility electron liquids (2DELs) needed for nanoscale quantum-electronic devices. Key parameters such as carrier densities, effective masses, and confinement thicknesses for 2DELs ...
WILEY2023Electronic Structure of InAs and InSb Surfaces: Density Functional Theory and Angle-Resolved Photoemission Spectroscopy
Gabriel Aeppli, Vladimir N. Strocov
The electronic structure of surfaces plays a key role in the properties of quantum devices. However, surfaces are also the most challenging to simulate and engineer. Here, the electronic structure of InAs(001), InAs(111), and InSb(110) surfaces is studied ...
WILEY2022Simultaneous Selective Area Growth of Wurtzite and Zincblende Self-Catalyzed GaAs Nanowires on Silicon
Anna Fontcuberta i Morral, Lucas Güniat, Valerio Piazza, Wonjong Kim, Vladimir Dubrovskii
Selective area epitaxy constitutes a mainstream method to obtain reproducible nanomaterials. As a counterpart, self-assembly allows their growth without costly substrate preparation, with the drawback of uncontrolled positioning. We propose a mixed approac ...
2021Fabrication of Single-Crystalline InSb-on-Insulator by Rapid Melt Growth
Anna Fontcuberta i Morral, Nicholas Paul Morgan, Heera Menon
InSb has the smallest bandgap and highest electron mobility among III-V semiconductors and is widely used for photodetectors and high-frequency electronic applications. Integration of InSb directly on Si would drastically reduce the fabrication cost and en ...
2021Differential Response of the Photoluminescence and Photocurrent of Polycrystalline CH(3)NH(3)PbI(3 )and CH3NH3PbBr3 to the Exposure to Oxygen and Nitrogen
László Forró, Endre Horvath, Andrzej Sienkiewicz, Márton Kollár, Anastasiia Glushkova, Konstantins Mantulnikovs
Because of their excellent photoelectric properties, organic-inorganic metal halide perovskites (MHPs), such as methylammonium lead triiodide, CH3NH3PbI3 (MAPbI(3)), and methylammonium lead tribromide, CH3NH3PbBr3 (MAPbBr(3)), are of great interest for the ...
AMER CHEMICAL SOC2019Impact of Strain and Alloy Disorder on the Electronic Properties of III-Nitride Based Two-dimensional Electron Gases
Over the past 20 years, III-nitrides (GaN, AlN, InN and their alloys) have proven to be an excellent material group for electronic devices, in particular, for high electron mobility transistors (HEMTs) operating at high frequency and high power. This is ma ...
