Optical detection and spatial modulation of mid-infrared surface plasmon polaritons in a highly doped semiconductor (2017)
Journal Article

Highly doped semiconductors (HDSCs) are promising candidates for plasmonic applications in the mid-infrared (MIR) spectral range. This work examines a recent addition to the HDSC family, the dilute nitride alloy In(AsN). Post-growth hydrogenation of...

Giant Quantum Hall Plateau in Graphene Coupled to an InSe van der Waals Crystal (2017)
Journal Article

© 2017 authors. Published by the American Physical Society. We report on a "giant" quantum Hall effect plateau in a graphene-based field-effect transistor where graphene is capped by a layer of the van der Waals crystal InSe. The giant quantum Hall e...

Enhancing optoelectronic properties of SiC-grown graphene by a surface layer of colloidal quantum dots (2017)
Journal Article

We report a simultaneous increase of carrier concentration, mobility and photoresponsivity when SiC-grown graphene is decorated with a surface layer of colloidal PbS quantum dots, which act as electron donors. The charge on the ionised dots is spatia... Read More about Enhancing optoelectronic properties of SiC-grown graphene by a surface layer of colloidal quantum dots.

Engineering p-n junctions and bandgap tuning of InSe nanolayers by controlled oxidation (2017)
Journal Article

Exploitation of two-dimensional (2D) van der Waals (vdW) crystals can be hindered by the deterioration of the crystal surface over time due to oxidation. On the other hand, the existence of a stable oxide at room temperature can offer prospects for s...

Mobility enhancement of CVD graphene by spatially correlated charges (2017)
Journal Article

The manuscript presents a strategy for enhancing the carrier mobility of single layer CVD graphene (CVD SLG) based on spatially correlated charges. Our Monte Carlo simulations, numerical modeling and the experimental results confirm that spatial corr... Read More about Mobility enhancement of CVD graphene by spatially correlated charges.
