英文摘要	We report low-temperature transport studies of parallel double quantum dots formed in GaSb/InAsSb core-shell nanowires. At negative gate voltages, regular patterns of Coulomb diamonds are observed in the charge stability diagrams, which we ascribe to single-hole tunneling through a quantum dot in the GaSb core. As the gate voltage increases, the measured charge stability diagram indicates the appearance of an additional quantum dot, which we suggest is an electron quantum dot formed in the InAsSb shell. We find that an electron-hole interaction induces shifts of transport resonances in the source-drain voltage from which an average electron-hole interaction strength of 2.9 +/- 0.3 meV is extracted. We also carry out magnetotransport measurements of a hole quantum dot in the GaSb core and extract level-dependent g factors and a spin-orbit interaction.; Swedish Research Council (VR); Swedish Foundation for Strategic Research (SSF); Knut and Alice Wallenberg Foundation (KAW); National Basic Research Program of China [2012CB932703, 2012CB932700]; National Natural Science Foundation of China [91221202, 91421303, 61321001]; SCI(E); ARTICLE; bahram.ganjipour@gmail.com; 16; 91
