Query: Coulomb blockade in Etched Single and Few Layer MoS2 Nanoribbons   Confinement in two-dimensional transition metal dichalcogenides is an
attractive platform for trapping single charge and spins for quantum
information processing. Here, we present low temperature electron transport
through etched 50-70nm MoS2 nanoribbons showing current oscillations as a
function of gate voltage. On further investigations current through the device
forms diamond shaped domains as a function of source-drain and gate voltage. We
associate these current oscillations and diamond shaped current domains with
Coulomb blockade due to single electron tunneling through a quantum dot formed
in the MoS2 nanoribbon. From the size of the Coulomb diamond, we estimate the
quantum dot size as small as 10-35nm. We discuss the possible origins of
quantum dot in our nanoribbon device and prospects to control or engineer the
quantum dot in such etched MoS2 nanoribbons which can be a promising platform
for spin-valley qubits in two-dimensional transition metal dichalcogenides.
