Dynamic secondary ion mass spectrometry DSIMS

Figure 8.15 (a) Concentration profiles of in bilayer samples of P3HT and rf-[60]PCBM annealed for 5 min at different temperatures as measured using dynamic secondary ion mass spectrometry (DSIMS). The thicknesses of the layers were normalized such that 0 nm is the... 

The chemical mapping of simple ions such as C, Na, and have been applied to the TOF-SIMS analysis of biological samples of organs, tissues, and cells [22-27,89,90], and 3D images of the elemental distributions [91] have also been obtained. In addition, lateral and 3D distributions of Na+, K+, Ca+, and isotope-labeled elements in cells can be obtained with dynamic secondary ion mass spectrometry (DSIMS) imaging techniques [91,92]. 

Molecular aggregation structure of the PS-PFACg diblock copolymer films along the normal direction to the surface was also examined by dynamic secondary ion mass spectrometry (DSIMS), which is a well-established tool for the depth profiling of polymer materials. The PFA weight fraction at the depth of z by DSIMS was given as follows.

The reptation dynamics and the interface structure relations in Table 2 have been demonstrated experimentally by a series of interdiffusion experiments with selectively deuterated HDH/DHD polymer interfaces using dynamic secondary ion mass spectroscopy (DSIMS - see Secondary ion mass spectrometry) and neutron reflectivity. The scaling laws for interdigitation and the complete concentration profiles for Rouse and reptation dynamics have also been calculated. ...
