Defect-engineering of liquid-phase exfoliated 2D semiconductors: stepwise covalent growth of electronic lateral hetero-networks
(2024)Two-dimensional (2D) in-plane heterostructures display exceptional optical and electrical properties well beyond those of their pristine components. However, they are usually produced by tedious and energy-intensive bottom-up ... -
Near Room Temperature Production of Segregated Network Composites of Carbon Nanotubes and Regolith as Multifunctional, Extra-Terrestrial Building Materials
(2024)Constructing a semi-permanent base on the moon or Mars will require maximal use of materials found in situ and minimization of materials and equipment transported from Earth. This will mean a heavy reliance on regolith ... -
Knot Architecture for Biocompatible and Semiconducting 2D Electronic Fiber Transistors
(2024)Wearable devices have generally been rigid due to their reliance on silicon-based technologies, while future wearables will utilize flexible components for example transistors within microprocessors to manage data. ... -
Inert Liquid Exfoliation and Langmuir-Type Thin Film Deposition of Semimetallic Metal Diborides
(2024)aphite is one of only a few layered materials that can be exfoliated into nanosheets with semimetallic properties, which limits the applications of nanosheet-based electrodes to material combinations compatible with the ... -
Production of Ultrathin and High-Quality Nanosheet Networks via Layer-by-Layer Assembly at Liquid-Liquid Interfaces
(2024)Solution-processable 2D materials are promising candidates for a range of printed electronics applications. Yet maximizing their potential requires solution-phase processing of nanosheets into high-quality networks with ... -
Tuning Deposition Conditions for VN Thin Films Electrodes for Microsupercapacitors: Influence of the Thickness
(2024)Vanadium nitride is a highly promising material for micro-pseudocapacitors when used as a bifunctional thin film, i.e. an electrode material and a current collector, owing to its remarkable electrical and electrochemical ... -

Using Electrical Impedance Spectroscopy to Separately Quantify the Effect of Strain on Nanosheet and Junction Resistance in Printed Nanosheet Networks
(2025)Many printed electronic applications require strain-independent electrical properties to ensure deformation-independent performance. Thus, developing printed, flexible devices using 2D and other nanomaterials will require ... -
Witnessing environment dimension through temporal correlations
(2024)We introduce a framework to compute upper bounds for temporal correlations achievable in open quantum system dynamics, obtained by repeated measurements on the system. As these correlations arise by virtue of the ... -
An investigation of spectroscopic diversity in the pre-peak regime of thermonuclear supernovae
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)As the most commonly found transient in the night sky due to their high intrinsic brightness, Type Ia supernovae (SNe Ia) have shown themselves to be powerful cosmological tools due to their standardisable nature. There ... -
Bose condensation in nonequilibrium quantum gases: An adventure in the thermodynamics of light and matter
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Nonequilibrium condensates in microcavities have been extensively analysed over the past decades. Like equilibrium condensates, they are characterised by a macroscopic population of the ground state, however, the system ... -
Self-assembled clusters of magnetically tilted dipoles

Radio Imaging Spectroscopy of Eruptions in the Solar Corona
(Trinity College Dublin. School of Physics. Discipline of Physics, 2025)Regularly, the Sun produces a variety of energetic explosive events, such as solar flares (sudden, intense bursts of electromagnetic radiation) and coronal mass ejections (CMEs) (large-scale expulsions of plasma and magnetic ... -
Tracking Solar Electron Beams from the Corona to the Heliosphere using Bayesian Methods
(Trinity College Dublin. School of Physics. Discipline of Physics, School of Physics, 2025)The Sun is an active star that produces the most powerful phenomena in the solar system, particularly flares and coronal mass ejections (CMEs). These violent explosions accelerate electrons and other solar energetic particles ... -
