Direct-write electrochemical nanofabrication of ultrasmall graphene devices
Xiao Liu, Colm Durkan
Graphene nano-ribbons, GNRs, are promising channel materials for next-generation ultra-miniaturised devices due to their exceptional electrical and thermal properties which arise f…
Electrostatic edge effects versus edge doping in graphene nanoribbons: a scanning gate microscopy and modelling study
Colm Durkan, Xiao Liu, Ed Saunders
The charge neutrality point (CNP) of graphene nanoribbons (GNRs) patterned by oxygen plasma etching moves towards zero as the ribbon narrows and, on 300 nm SiO2, changes sign below…
Ferrotronics for the creation of band gaps in Graphene
Qifang Wan, Zhuocong Xiao, Ahmed Kursumovic +2
We experimentally demonstrate a simple graphene/ ferrolectric device, termed Ferrotronic (electronic effect from ferroelectric) device in which the band-structure of single-layer g…
Unravelling the electrical properties of epitaxial Graphene nanoribbons
Zhuocong Xiao, Colm Durkan
The size-dependent electrical resistivity of single-layer graphene ribbons has been studied experimentally for ribbon widths from 16 nm to 320 nm. The experimental findings are tha…
Periodic ripples on thermally annealed Graphene on Cu (110) - Surface reconstruction or Moire pattern?
Colm Durkan
We have used Ultrahigh Vacuum (UHV) Scanning tunneling microscopy (STM) to investigate the effect of thermal annealing of graphene grown by chemical vapour deposition (CVD) on a Cu…
Towards Resolving Landauer's Paradox Through Direct Observation of Multiscale Ferroelastic-Ferroelectric Interplay
Colm Durkan, Asaf Hershkovitz, DaPing Chu +2
Electric-polarization reversibility in nano-ferroelectric structures renders them as a convenient platform for exploring phase transitions and developing energy-efficient switching…
