Figure 2

From: Experimental realisation of tunable ferroelectric/superconductor \(({\text {B}} {\text {T}} {\text {O}}/{\text {Y}} {\text {B}}{\text {C}} {\text {O}})_{{\text {N}}}/{\text {S}}{\text {T}}{\text {O}}\) 1D photonic crystals in the whole visible spectrum

Figure 2

Electron diffraction pattern for (a) YBCO and (b) BTO layers with different crystal orientations are displayed. (c) TEM image for \({{\hbox {(BTO/YBCO)}}}_{N=1}\) with associated [001] and [010] crystal directions. Zoom of HRTEM images for (d) YBCO, and (e) BTO, respectively. A sketch of the crystal structure displays the atomic positions.
