CuFe2O4/MoS2 Mixed-Dimensional Heterostructures with Improved Gas Sensing Response
Abstract Mixed-dimensional (2D + nD, n = 0, 1, and 3) heterostructures opened up a new avenue for fundamental physics studies and applied nanodevice designs. Herein, a novel type-II staggered band alignment CuFe2O4/MoS2 mixed-dimensional heterostructures (MHs) that present a distinct enhanced (20–28...

Abstract Mixed-dimensional (2D + nD, n = 0, 1, and 3) heterostructures opened up a new avenue for fundamental physics studies and applied nanodevice designs. Herein, a novel type-II staggered band alignment CuFe2O4/MoS2 mixed-dimensional heterostructures (MHs) that present a distinct enhanced (20–28%) acetone gas sensing response compared with pure CuFe2O4 nanotubes are reported. Based on the structural characterizations and DFT calculation results, the tentative mechanism for the improvement of gas sensing performance of the CuFe2O4/MoS2 MHs can be attributed to the synergic effect of type-II band alignment and the MoS2 active sites. |
