Abstracts

EN

By combination of polarization-resolved photoluminescence, transport, and realistic numerics we study energy and recombination spectra of free and acceptor-bound positive trions in a quasi-two-dimensional hole gas. The singlet-triplet crossing in the trion ground state is found at B≈12 T, and a slight reduction of all trion binding energies coincident with the formation of a Laughlin hole fluid is observed at B≈14.2 T.
