Informal science institutions (ISIs) are beginning to adopt mobile technology to support interpreters (docents), but not much is known about how to design these supports. One approach to designing technology for new scenarios is participatory design (PD), where end-users are involved as experts in the task domain who can help envision the application of(More)
We report on electronic transport measurements of dual-gated nanodevices of the low-carrier density topological insulator (TI) Bi_{1.5}Sb_{0.5}Te_{1.7}Se_{1.3}. In all devices, the upper and lower surface states are independently tunable to the Dirac point by the top and bottom gate electrodes. In thin devices, electric fields are found to penetrate through(More)
