Highly Conductive n-Al0.65Ga0.35N Grown by MOCVD Using Low V/III Ratio

open access: yesCrystals, 2021
Highly conductive silicon-doped AlGaN and ohmic contacts are needed for deep-UV LEDs and ultrawide bandgap electronics. We demonstrate improved n-Al0.65Ga0.35N films grown by metal–organic chemical vapor deposition (MOCVD) on sapphire substrates using a ...

From birds to bees: applying video observation techniques to invertebrate pollinators

open access: yesJournal of Pollination Ecology, 2012
Observation is a critical element of behavioural ecology and ethology.  Here, we propose a similar set of techniques to enhance the study of the diversity patterns of invertebrate pollinators and associated plant species.
