Flexible Solar-Blind Ga₂O₃ Ultraviolet Photodetectors With High Responsivity and Photo-to-Dark Current Ratio

IEEE Photonics Journal, 2019
In this work, flexible solar blind Ga2O3 ultraviolet photodetectors with high responsivity and photo-to-dark current ratio are demonstrated. The Ga2O3 films are obtained by the RF magnetron sputtering method on flexible polyimide (PI) substrates and the ...

Fractal photonic bandgap fibers

Optics Express, 2020
Photonic bandgap fibers have a critical constraint determined by wavelength. The principle of scale invariance requires that features remain unchanged even as the scale of an object changes. This paper introduces a new concept for fractal photonic crystal fibers integrating these two.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

High-Voltage β-Ga2O3 Schottky Diode with Argon-Implanted Edge Termination

Nanoscale Research Letters, 2019
The edge-terminated Au/Ni/β-Ga2O3 Schottky barrier diodes were fabricated by using argon implantation to form the high-resistivity layers at the periphery of the anode contacts.

Predicting Structural and Optical Properties of Hollow-Core Photonic Bandgap Fibers from Second Stage Preforms

, 2013
We propose a simple theory based on mass conservation that allows accurate prediction of guidance properties in hollow-core photonic bandgap fibers (HC-PBGF) from knowledge of the second stage preforms from which the fibers are ...

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

Advanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,
