Fast silicon photodiodes

open access: yesNature Photonics, 2017
How much internet traffic did you generate today? Perhaps more than you realise given the increasing popularity of streaming audio or video content, “cloud” data storage, and social media. It is estimated that approximately 1 zettabyte (1021 bytes) of internet traffic was transmitted globally last year,1 which is the equivalent of about 360MB per day ...

Multiwavelength Implantable Oximeter for Wireless Monitoring of Tissue Oxygenation in the Presence of Blood Volume Changes

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an implantable, wireless, battery‐free oximeter that can continuously monitor physiologically consistent regional tissue oxygenation under dynamic changes of blood volume. This is achieved through multiwavelength photoplethysmography and validated both via Monte Carlo simulations and in vivo rat studies. Different stress events were

Hole dangling-bond capture cross-sections in a-Si:H [PDF]

open access: yes, 2013
It is demonstrated that the occupation statistics for a Gaussian distribution of dangling bond states may account for the measured variation of hole mobility-lifetime values in hydrogenated amorphous silicon as the Fermi energy is systematically varied ...

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films

open access: yesAdvanced Materials, EarlyView.
ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.
