The devices are operated with gates above and below the WSe2 layer to accumulate a hole gas\, which for some devices is then selectively depleted to define the dot. Temperatu re dependence of conductance in the Coulomb-blockade regime is consistent w ith transport through a single level\, and excited-state transport through the dots is observed at temperatures up to 10 K. These devices provide a pl atform to evaluate valley-spin states in monolayer and bilayer WSe2 for app lication as qubits. Finally\, I will discuss some of the new experiments m ade possible by these devices.
