  Low-temperature transport spectroscopy measurements on a quantum dot
lithographically defined in a multiwall $\mathrm{MoS}_2$ nanotube are
demonstrated. At $T=300\,\mathrm{mK}$, clear Coulomb blockade is observed, with
charging energies in the range of 1 meV. In single-electron tunneling, discrete
conductance resonances are visible at finite bias. Additionally, a magnetic
field perpendicular to the nanotube axis reveals clear indications of quantum
state transitions, with effective $g$ factors consistent with published
theoretical predictions.
