The role of device asymmetries and schottky barriers on the helicity-dependent photoresponse of 2d phototransistors

HIGHLIGHTS

• who: Jorge Quereda from the (UNIVERSITY) have published the Article: The role of device asymmetries and Schottky barriers on the helicity-dependent photoresponse of 2D phototransistors, in the Journal: (JOURNAL)
• what: To clarify the role of Schottky barriers the authors investigate helicity-dependent photocurrents in 1L-MoSe2 devices both with direct metal/MoSe2 contacts and with metal/h-BN/MoSe2 tunnel contacts. Dependence of CPC on the gate voltage Next, the authors investigate the effect of the gate voltage on the photocurrent.
• how: This result is consistent with the earlier measurements in hBN . . .
