Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Orthogonal Passivation of Polar Facets for Efficient InSb Quantum Dot SWIR Photodetectors

open access: yesAdvanced Materials, EarlyView.
An orthogonal passivation strategy is developed for indium antimonide (InSb) colloidal quantum dots (CQDs): a metal halide passivates Sb‐terminated surface sites, while thiol ligands passivate In‐terminated sites. This site‐specific passivation reduces trap density, prolonging carrier lifetime and increasing carrier mobility, and enables InSb CQD ...

2-5m InAs/GaSb superlattices infrared photodetector

open access: yes, 2011
High quality InAs/GaSb type-II band alignment superlattices infrared photodetectors with different InAs thicknesses were grown on GaSb and GaAs substrates by molecular beam epitaxy(MBE). The detection wavelengths of these InAs/GaSb SLs infrared detectors

Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

open access: yesAdvanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...

Interface Dynamics in Biomolecular Condensates by High‐Speed AFM

open access: yesAdvanced Materials Interfaces, EarlyView.
High‐speed atomic force microscopy provides nanoscale structural dynamics at the liquid interface of biomolecular condensates, key elements in several cellular pathways. By addressing the challenges of low surface tension and condensate‐induced instabilities, we achieve nanometer spatial and sub‐second temporal resolution, revealing structural ...

A new method to reduce the dark current of GaN based Schottky barrier ultraviolet photodetector

open access: yes, 2008
A new method to reduce the dark current of GaN based Schottky barrier ultraviolet photodetector is proposed. In comparision with conventional i-CaN/n(+)-GaN structure, an additional thin p-GaN cap layer is introduced on the i-GaN(n(-)-GaN) in the new ...

Optimal subwavelength design for efficient light trapping in central slit of plasmonics-based metal-semiconductor-metal photodetector

open access: yes, 2015
© 2015, Springer Science+Business Media New York. We present the analysis of a novel plasmonics-based metal-semiconductor-metal photodetector that dramatically modifies the light transmission spectra when the sub-wavelength central slit is partly covered
