Step-flow growth of graphene-boron nitride lateral heterostructures by molecular beam epitaxy
(The University of Nottingham, 2020-04-20)
Integration of graphene and hexagonal boron nitride (hBN) into lateral heterostructures has drawn focus due to the ability to broadly engineer the material properties. Hybrid monolayers with tuneable bandgaps have been ...
Room temperature up-conversion electroluminescence from a mid-infrared In(AsN) tunnelling diode
(applied physics letters, 2020-04-01)
Light emitting diodes (LEDs) for the mid-infrared (MIR) spectral range require material systems with tailored optical absorption and emission at wavelengths > 2 μm. Here, we report on MIR LEDs based on In(AsN)/(InAl)As ...
Fluorescence and electroluminescence of J-aggregated polythiophene monolayers on hexagonal boron nitride
(The University of Nottingham, 2020-09-15)
The photophysics of a semiconducting polymer is manipulated through molecular self-assembly on an insulating surface. Adsorption of polythiophene (PT) monolayers on hexagonal boron nitride (hBN) leads to a structurally-induced ...
