The aim is to explore how thickness variations in 2H-MoTe2 influence interfacial states and polarization switching in BaTiO3.
Thickness variations of 2H-MoTe2 from 18 to 20 unit cells
Measurement of work function shifts and conduction mechanisms
Analysis of polarization state reversals
A 0.44 eV work function shift occurred due to thickness variation
Reversal of BaTiO3 polarization state from P_up to P_down
Electrical transport changed to Fowler-Nordheim tunneling under polarization
