In this paper, we present experimental measurements of slip length of deionized (DI) water flow on a silicon surface and a graphite surface by using atomic force microscope. The results show that the measured hydrodynamic drag force is higher on silicon surface than that on graphite surface, and a measured slip length about 10 nm is obtained on the later surface.

AMF anodization lithography was performed on organic thin films with conducting polymers which is poly(3,4-ethylenedioxythiophene). The conductivity of PEDOT thin films was changed by different dopants and organic solvents. Two different dopants are poly(4-styrenesulfonate) and di(2-ethylhexyl)-sulfosuccinate. Also, DMF and IPA were used to prepare the PEDOT thin films doped with PSS and DEHS on silicon surface. The conductivities of these PEDOT variants were compared by obtaining their I–V curves between tip and thin films using AFM. Silicon oxide nanopatterns with higher aspect ratios can be obtained from the films with higher conductivity.

The cantilevers of atomic force microscope (AFM) are mounted under a certain tilt angle, which is commonly assumed to have negligible effect on friction measurements in AFM. We present a theoretical study of the effect of the tilt angle on AFM based friction measurements. A method for correcting the friction coefficient between sample surfaces and AFM tips is also presented to minimize the effects of the tilt. The frictional forces between a silicon tip and a silicon surface at tilt angles ranging from 5 degrees to 25 degrees were measured. The results show that the measured friction coefficient increases with the tilt angle effectively, whereas the variation range of the corrected friction coefficient is within 10%.

Both one-dimensional (1D) and two-dimensional (2D) slope distributions were obtained from the surface topographic data, measured using an atomic force microscope for a rough silicon surface. The resulted slope distributions deviate significantly from the Gaussian distribution, with noticeable side peaks. The bidirectional reflectance distribution function (BRDF) of the same surface, measured with a laser scatterometer at 635 nm and 785 nm, exhibits subsidiary peaks. The measured slope distributions are implanted into a geometric optics model to predict the in-plane BRDF for different azimuthal angles. The 1D slope distribution has some success in predicting the BRDF at limited azimuthal angles, but is not applicable to other cases. On the other hand, the BRDF predicted using the 2D slope distribution matches well with the experimental results for any azimuthal angles. The method developed here may also help predict the BRDF for other rough surfaces with microstructures.

This paper investigates nanomachining of single-crystal silicon using an atomic force microscope with a diamond-tip cantilever. To enable nanomachining of silicon, a nanomachining cantilever with a pyramidal diamond tip was developed using a combination of photolithography and hot-filament chemical vapor deposition. Nanomachining experiments on silicon using the cantilever are demonstrated under various machining parameters. The silicon surface can be removed with a rate of several tens to hundreds of nanometers in ductile mode, and the cantilever shows superior wear resistance. The experiments demonstrate successful nanomachining of single-crystal silicon.
