In ultrahigh vacuum Atomic Force Microscopy(UHVAFM), the frequency of an oscillator holding the scanning tip takes a typical Lennard-Jones like curve with a local minima just before contact. We demonstrate here the application of a control scheme to

Heterodyne laser Doppler interferometry was used to implement a high frequency atomic force microscope (AFM) that can accommodate a cantilever with a natural frequency of up to 200 MHz. Since Doppler interferometry measures velocity, the signal level

Suspended highly oriented pyrolytic graphite (HOPG) nanosheets (10?300?nm thick) were created by direct mechanical cleavage of a bulk HOPG crystal onto silicon micropillars and microtracks. We show that suspended HOPG nanosheets can be used to engine

We report the surface-tension-powered self-assembly (displacement, alignment, pulling down and locking) of microcantilevers. Capillary forces-assisted displacement is realized by compression of four arrays of springs linked to the opposite lateral si

Controlled and reproducible combing of λ-phage DNA molecules can be realized in predetermined orientations on highly oriented pyrolitic graphite (HOPG) surfaces. Observations by atomic force microscopy (AFM) show that DNA adsorption onto HOPG surfac

A major problem of dynamic mode atomic force microscopy has been the necessity to employ relatively large amplitude of drive of the cantilever in the few Angstrom to the nm range to allow for sustaining self-excitation, and to obtain sufficient signa

The adsorption of molecular oxygen on the c(2 × 8) reconstruction of quenched Si(1 1 1) surfaces has been studied at the atomic scale using scanning tunneling microscopy (STM) at room temperature (RT). It has been found that clean well reconstructed

The coexisting metastable reconstructions of the Si(111) surface have been investigated by non contact-atomic force microscopy (NC-AFM). True atomic resolution has been achieved in the NC-AFM imaging of the 7× 7, c(2× 8), 2× 2, c(2× 4), and √3

An atomic force microscope that mounts on a sample stage of a scanning force microscope (SEMAFM) was developed. It was implemented for measurement of static mechanical properties of three-dimensional nanometric objects. The sample stage of the AFM wa
