Example text

New developments in STM techniques including SP-STM and MP-STM are discussed in comparison with conventional non-magnetic and single tip STM methods. SP-STM is able to detect the local magnetization of the surface below the apex of the STM tip by making it sensitive to the spin of the tunneling electron. It can image the magnetic domain structure of the sample with ultimate resolution down to the atomic scale. MP-STM offers a versatile tool for electrical transport measurements at the nanometer scale.

Xu et al. (a) (b) (c) (d) Fig. 8. 6 V (b). The scan size is 150 × 150 ˚ A. 5 V (d) bias voltages, which are given with respect to the valence-band maximum. Adapted from Ref. 42. 45 On GaAs(0 0 1), the c(8 × 2) domains are usually surrounded by (n × 6) domains which are one atomic layer higher. 42 Triple-protrusion rows can be clearly seen in both images, where the bright rows are separated by dark trenches and the distance between the centers of two adjacent trenches. 5 V sample bias respectively, and the theoretical STM images in good agreement with the experimentally observed images shown in Figs.
