## Description

- description: Few-layer-thick transition metal dichalcogenides have recently been
    found to exhibit discrete subbands, called van der Waals quantum well (vdW-QW)
    states, owing to the out-of-plane quantum confinement. The vdW-QW in the conduction
    band (CB) remained unelucidated due to the difficulty to access these states with
    conventional methods. Here we investigate the vdW-QW in the CB of 3- layer (3L)
    WSe2 using resonant tunneling in 3L WSe2/h-BN/3L WSe2 junction under the control
    of inter-layer twist angle θint between two WSe2 layers. Measured current–voltage
    characteristics exhibit multiple resonant tunneling peaks, and their positions
    are continuously modulated in the broad range of θint from 0 to 60°. The results
    showed good agreement with calculated angular dispersion of the CB, including
    a crossing of spin-polarized subbands and a presence of saddle point. Our twist-controlled
    resonant tunneling overcome difficulties in measuring the momentum-resolved electronic
    structure and unveil the unique vdW-QW structure in the CB of 3L-WSe2.
