英文摘要	We demonstrate direct measurements of the spin-orbit interaction and Lande g factors in a semiconductor nanowire double quantum dot. The device is made from a single-crystal pure-phase InAs nanowire on top of an array of finger gates on a Si/SiO2 substrate and the measurements are performed in the Pauli spin-blockade regime. It is found that the double quantum dot exhibits a large singlet-triplet energy splitting of Delta(ST) similar to 2.3meV, a strong spin-orbit interaction of Delta(SO) similar to 140 mu eV, and a large and strongly level-dependent Lande g factor of similar to 12.5. These results imply that single-crystal pure-phase InAs nanowires are desired semiconductor nanostructures for applications in quantum information technologies.
