Measuring the Electronic Bandgap of Carbon Nanotube Networks in Non-ideal p-n Diodes
Gideon Oyibo, Thomas Barrett, Sharadh Jois +2
The measurement of the bandgap in quasi-one dimensional materials such as carbon nanotubes is challenging due to its dimensionality. In this work, we measure the electronic bandgap…
All-carbon nanotube solar cell devices mimic photosynthesis
Gideon Oyibo, Thomas Barrett, Sharadh Jois +2
Photovoltaics has two main processes: Optical absorption and power conversion. In photosynthesis, the two equivalent processes are optical absorption and chemical conversion. Where…
Universally Expressive Communication in Multi-Agent Reinforcement Learning
Matthew Morris, Thomas D. Barrett, Arnu Pretorius
Allowing agents to share information through communication is crucial for solving complex tasks in multi-agent reinforcement learning. In this work, we consider the question of whe…
Learning to Solve Combinatorial Graph Partitioning Problems via Efficient Exploration
Thomas D. Barrett, Christopher W. F. Parsonson, Alexandre Laterre
From logistics to the natural sciences, combinatorial optimisation on graphs underpins numerous real-world applications. Reinforcement learning (RL) has shown particular promise in…
Reinforcement Learning for Branch-and-Bound Optimisation using Retrospective Trajectories
Christopher W. F. Parsonson, Alexandre Laterre, Thomas D. Barrett
Combinatorial optimisation problems framed as mixed integer linear programmes (MILPs) are ubiquitous across a range of real-world applications. The canonical branch-and-bound algor…
