On the switching mechanism and optimisation of ion irradiation enabled 2D memristors
Samuel Aldana, Jakub Jadwiszczak, Hongzhou Zhang
Memristors are prominent passive circuit elements with promising futures for energy-efficient in-memory processing and revolutionary neuromorphic computation. State-of-the-art memr…
Defect-Moderated Oxidative Etching of MoS2
Pierce Maguire, Jakub Jadwiszczak, Maria O'Brien +4
We report a simple technique for the selective etching of bilayer and monolayer MoS. In this work, chosen regions of MoS were activated for oxygen adsorption and reaction b…
Photoresponsivity enhancement in monolayer MoS by rapid O:Ar plasma treatment
Jakub Jadwiszczak, Gen Li, Conor P. Cullen +5
We report up to ten-fold enhancement of the photoresponsivity of monolayer MoS by treatment with O:Ar (1:3) plasma. We characterize the surface of plasma-exposed MoS by…
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…
Defect Sizing, Separation and Substrate Effects in Ion-Irradiated Monolayer 2D Materials
Pierce Maguire, Daniel S. Fox, Yangbo Zhou +8
Precise and scalable defect engineering of 2D nanomaterials is acutely sought-after in contemporary materials science. Here we present defect engineering in monolayer graphene and…
