After a Ramsay Fellowship in the Department of Chemistry at UCL, he was appointed to a Lectureship (2013), Reader (2016) and Professor of Computational Materials Design (2018) at UCL and Diamond Light Source. Scanlon received his degree in Computational Chemistry (2006) and PhD in Chemistry (2011) from Trinity College Dublin, Ireland. His project is sponsored by Diamond Light Source Ltd., where he works closely with the HAXPES beamline I09, under the supervision of Dr Tien-Lin Lee.ĭavid O. His research is primarily focussed on understanding the defect chemistry of transparent conductors and high mobility semiconductors. He is now working towards an EngD in Molecular Modelling and Materials Science under the supervision of Professor David O. Joe Willis received his BSc (2018) in Chemistry and MRes (2019) in Molecular Modelling and Materials Science at UCL. The smorgasbord of materials presented in this review should guide experimental and computational scientists alike in the next phase of p-type transparent conductor research. We find that phosphides, selenides, tellurides and halides are the most promising emerging materials, capable of achieving greater valence band dispersion than traditional oxides, and we discuss the challenges facing these more exotic systems. We discuss the impact of high-throughput screening studies on materials discovery and critically assess the family of p-type halide perovskites that emerged from these, ruling them as unsuitable candidates for high-performance applications. This review will cover the basic theory and design principles of transparent conductors, followed by an overview of early p-type TCMs and their shortcomings. However, these new technologies rely heavily on the development of high performance p-type TCMs, a task that has posed a significant challenge to researchers for decades. The market for transparent electronics is projected to surpass $3.8 billion by 2026 as the automotive industry seek to incorporate pop-up displays into driver windshields, and the prospect of touch-enabled transparent displays challenges the traditional mouse and keyboard mode of computer operation. More than ever we rely on display and touch screens, energy efficient windows and solar cells in our day to day lives. Transparent conducting materials (TCMs) are crucial in the operation of modern opto-electronic devices, combining the lucrative properties of optical transparency and electronic conductivity.
