Advanced Functional Materials, EarlyView.Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

Interface Effects in Ultrathin Silicon on Insulator Films
Advanced Functional Materials, EarlyView.This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Optical trapping: optical interferometric metrology and nanophotonics
, 2010 The two main themes in this thesis are the implementation of interference methods with optically trapped particles for measurements of position and optical phase (optical interferometric metrology) and the optical manipulation of nanoparticles for ...

Advanced Functional Materials, EarlyView.All‐solution‐processed, low‐cost extended short‐wavelength infrared photodetectors are realized by coupling colloidal HgTe quantum dots to plasmonic In2O3:Sn,F nanocrystals. Localized surface plasmon resonances boost and spectrally tailor light absorption between 1500 and 3000 nm, enabling responsivities above 40 A W−1.

Advanced Healthcare Materials, EarlyView.Packed hydrogel microfiber (PHM) materials consist of flexible and high aspect ratio hydrogel components that, as a bulk material, are simultaneously mechanically robust and dynamic. Cells cultured in or on PHM scaffolds can be influenced by topographical cues or interact with a dynamic environment that permits cell spreading and multicellular ...

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy
Advanced Healthcare Materials, EarlyView.Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Space charge determination in HVDC power cable and its influence on electric field
, 2010 Considerable amount of transmission and distribution of electricity is carried out by power cable. At present, most high voltage direct current (HVDC) installation uses traditional (oil-impregnated paper insulation and oil-filled-types) cables which pose
