Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling
Small, EarlyView.Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Formation of Gallium-induced nanostructures on single crystal HOPG surface
, 2011 The room temperature growth of gallium atoms on the highly oriented pyrolytic graphite (HOPG) surface has been performed. The gallium atoms were deposited by thermal evaporation method in an ultra high vacuum system at a base pressure 5 × 10−10 torr. The

Crystallinity Effects on Near‐Infrared Photoresponse in Y6‐Based Organic Phototransistors
Small, EarlyView.Solution‐processed Y6 thin films are investigated as active layers of organic field‐effect transistors and as near‐infrared photodetectors. Enhanced crystallinity in Y6 films induced by thermal annealing leads to improved charge transport and pronounced photoresponsivity.

AFM Induced Local Oxidation of HOPG
MRS Proceedings, 2014 ABSTRACTAFM induced local anodic oxidation of HOPG was carried out in various conditions such as humidity, applied voltage and scan speed. A clear evidence of different oxidation features between HOPG and graphene has been confirmed and discussed.These results should contribute to the progress of the micro/nano fabrication of graphene by the local ...

Small, EarlyView.Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

Small Methods, EarlyView.Microspectroscopy combines a standard optical microscope with a spectrometer to measure reflectance and transmittance of samples down to the microscale. A numerical formalism that explicitly accounts for the high numerical aperture of magnifying optics retrieves complex refractive indices.
