Sirringhaus Lab
Hyeonmin Choi is a PhD student at Seoul National University (SNU), studying charge transport in perovskite field-effect transistors. He is conducting his research under the supervision of Prof. Keehoon Kang. During his time at the group he is focussing on AC Hall measurements of 2D tin perovskites to better understand how temperature treatments can improve mobility.
Contact-Limited Temperature Dependence Paper Published in Journal of Physics: Materials
2 April 2025
We have recently published the paper Elucidating Contact-Limited Temperature Dependence of Charge Transport in 2D Tin Halide Perovskite Field-Effect Transistors in Journal of Physics: Materials . Two-dimensional tin halide perovskites have recently generated significant interest due to their ease of processing and high...
Sirringhaus Lab Members Attend innoLAE 2025
20 February 2025
Seven members of the Sirringhaus Lab attended the conference innoLAE (Innovations in Large-Area Electronics) over the previous two days. The event, hosted at Magdalene College, Cambridge , included dozens of talks from both academics and industry experts across a wide range of topics, from applications like biosensors and...
Nernst Effect Paper Published in Nature Communications
11 February 2025
Our paper Observation of Anomalously Large Nernst Effects in Conducting Polymers has now been published in Nature Communications ! While the Nernst effect is well-documented in inorganic semiconductors and metals, this phenomenon is typically negligible in polymers with lower structural order and an inherently low mobility...
