Research from the Stavropoulos Center for Complex Quantum Matter has been selected for the cover of Advanced Functional Materials. Published in Volume 36, Issue 72, highlighting the Center's recent work on the origin of unusual electronic and magnetic behavior in the widely studied Ti3C2Tx MXene.
The research article, “Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene,” reveals that nanoscale titanium suboxide phases confined between MXene layers play a key role in several puzzling property changes observed near room temperature. In particular, minority Ti3O5 phases undergo structural and electronic transitions that modify the MXene's interlayer spacing, electronic structure, and spin dynamics.
The study was led by Bence G. Márkus, László Forró, and Dávid Beke, together with Bradlee J. McIntosh, Lili Vajtai, Anna Nyáry, Sándor H. Sipos, Nirmal J. Ghimire, and Ferenc Simon. The work provides new insight into the microscopic origin of temperature-dependent behavior in Ti3C2Tx and highlights how minority phases can strongly influence the functional properties of two-dimensional materials.
