Suppression of the Shear Raman Mode in Defective Bilayer MoS2
Pierce Maguire, Clive Downing, Jakub Jadwiszczak +7
We investigate the effects of lattice disorders on the low frequency Raman spectra of bilayer MoS2. The bilayer MoS2 was subjected to defect engineering by irradiation with a 30 ke…
Neuromorphic MoS2 memtransistors fabricated by localised helium ion beam irradiation
Jakub Jadwiszczak, Darragh Keane, Pierce Maguire +12
Two-dimensional layered semiconductors have recently emerged as attractive building blocks for next-generation low-power non-volatile memories. However, challenges remain in the co…
Environmental effects on the electrical characteristics of back-gated WSe2 field effect transistors
Francesca Urban, Lisanne Peters, Nadia Martucciello +2
We study the effect of polymer coating, pressure and temperature on the electrical characteristics of monolayer WSe2 back-gated transistors with quasi-ohmic Ni/Au contacts. We find…
A WSe2 vertical field emission transistor
Antonio Di Bartolomeo, Francesca Urban, Maurizio Passacantando +6
We report the first observation of gate-controlled field emission current from a tungsten diselenide (WSe2) monolayer, synthesized by chemical-vapour deposition on SiO2/Si substrat…
Optimized single-layer MoS2 field-effect transistors by non-covalent functionalisation
HyunJeong Kim WungYeon Kim, Maria O'Brien, Niall McEvoy +6
Field-effect transistors (FETs) with non-covalently functionalised molybdenum disulfide (MoS2) channels grown by chemical vapour deposition (CVD) on SiO2 are reported. The dangling…
Highly sensitive electromechanical piezoresistive pressure sensors based on large-area layered PtSe films
Stefan Wagner, Chanyoung Yim, Niall McEvoy +8
Two-dimensional (2D) layered materials are ideal for micro- and nanoelectromechanical systems (MEMS/NEMS) due to their ultimate thinness. Platinum diselenide (PtSe), an excit…
