Based on the high readout speed of 1 000 - 8 000 fps (depending onwindowing and binning mode), the pnCCD (S)TEM camera gives the possibility to investigate chemical or physical processes in the 0.1 - 1 ms regime. The example below shows an experiment where the induced resonant oscillation of a freestanding CdS nanowire was measured. The readout of the camera was externally triggered with a variable delay with respect to the zero crossing of the sine function driving the oscillation with 1.85 kHz. In the analysis of the measu-rement, the position of the nanowire revealed the resonant frequency of the nanowire to be approximately 4 times the excitation frequency. Elastic properties of the nanowire can be deduced from these measurements through further analysis.
