Fig. 2: Crystallographic properties of BTO films on graphene/Ge.
From: Highly heterogeneous epitaxy of flexoelectric BaTiO3-δ membrane on Ge
XRD results of BTO/graphene/Ge (001) heterostructure: a specular 2θ scan and pole figures using b BTO (101) Bragg conditions and c Ge (111) Bragg conditions. XRD results of BTO/graphene/Ge (011) heterostructure: d specular 2θ scan and pole figures using e BTO (101) Bragg conditions and f Ge (111) Bragg conditions. g Cross-sectional TEM image of the BTO /graphene/Ge (001) heterostructure. h SAED pattern of the sample is shown in g. Orange squares mark Ge diffraction dots while blue rings denote the BTO diffraction dots region. i Cross-sectional TEM image of the BTO/graphene/Ge (011) heterostructure. j SAED pattern of the sample shown in i. Orange squares mark Ge diffraction dots while blue circles denote BTO diffraction dots.
