Scanning photo-induced impedance microscopy
WebScanning Photo-Induced Impedance Microscopy (SPIM) is an impedance imaging technique that is based on photocurrent measurements at field-effect structures. The material under investigation is deposited onto a semiconductor–insulator substrate. A thin metal film or an electrolyte solution with an immersed electrode serves as the gate … WebFinally, we show in Fig. 6.13 the scan impedance for scanning at 30°, 45°, and 60°, respectively, in the H plane, while Fig. 6.14 shows the f - plane scan at the same scan angles. Compared to the single-slab cases shown in Figs. 6.8 and 6.9, we observe that the double-slab case continues to be superior to the single-slab...

A possible reason for this discrepancy is the optical setup used in these experiments. Diffusion ... WebIn contrast to AFM-IR, a closely related technique that has been developed over the last decade, photo induced force microscopy (PiFM), delivers spectra that compare very closely to those from far field infrared spectroscopy (although subtle differences may arise). 25 PiFM therefore offers an exciting new window into local surface chemistry with all the …
