LTO Changes (IMAGE)
Caption
The resistance of LTO changes with increasing and decreasing pressure, the insets show the corresponding structures at different pressure regions. It indicates that LTO undergoes crystalline-distortion-amorphous transitions under high pressure. The resistance increases at lower pressures during the lattice distortion, then it starts to decrease sharply as amorphization takes place at higher pressure. The amorphous LTO can be decompressed down to ambient pressure and has much better conductivity compares with the crystalline LTO.
