Saulius Marcinkevicius with Prof. James S. Speck from University of California, Santa Barbara have determined the time for hole self-trapping in b-Ga2O3, a material with a high potential in power electronics. So far, the hole self-trapping into a polaron state is an ultrafast process that has been elusive for direct measurements. The ultrafast pump-probe measurements performed at KTH have revealed the hole self-trapping time to be 0.5 ps at 300 K. The study has been published in Applied Physics Letters, doi.org/10.1063/5.0003682
