I-V curves for (a) undoped GST, GST with oxygen contents of: (b) 16.7%, (c) 21.7%, and (d) 30.8%. Threshold voltages are indicated with vertical dashed lines in each figure. The melting down voltage of the GST with a 30.8% oxygen content is also indicated as a dashed line in (d). The first and second sweeps are indicated by black lines and red dots, respectively.
AFM images of GST films with oxygen contents of: (a) 16.7%, (b) 21.7%, and (c) 30.8%, after an annealing treatment at .
A complex impedance diagram of GST films with oxygen contents of 16.7% and 21.7% after an annealing treatment at . The smaller intercept of the abscissa indicates the resistance of the grain while the larger one indicates the sum of and the resistance of the grain boundary .
Intensity of desorbed molecules (left axis) and temperature (right axis) for (a) an as-grown GST film, as-grown GST films with oxygen contents of: (b) 16.7% and (c) 30.8% are plotted as a function of heating time. The temperature increases up to (right axis) for 27 min and is then constant up to 60 min.
