In this paper the Al2O3 nanowire is grown on silicon chips by electrochemical reaction under AFM probe. The obtained Al2O3 nanowire is regular arranged, the length and width of the nanowire can be controlled by adjusting applied voltage and scanning rate of AFM probe
The standard application of atomic force microscope (AFM) is observation with subnanometer resolution. As development of nano-tech, AFM has also become popular as a simple manipulation tool. We have proved that developing a haptic user interface (HUI) can significantly improve these functions of AFM. When going on observation, under the assistance of HUI, the user can not only observe surface characters...
The study on small molecular space morphology of nanometer material by a high-resolution Atomic Force Microscopy (AFM) is introduced in this paper. The high-resolution AFM.IPC-208B was developed by Chongqing University, and its precision: lateral resolution is 0.1 nm, vertical resolution is 0.01 nm. Applying AFM.IPC-208B, we obtained the surface structures of five samples (natural white mica, polyimide,...
In this paper, The datum line assessing surface roughness parameters and main three profile height parameters of surface roughness are introduced in detail, and the emphasis is laid on the operation principle of Atomic Force Microscopy Institute of Particle Physics Chongqing University (AFM.IPC-208B) and its software implementation method on the nanometer scale surface roughness measurement. The three-dimensional...
Ideally the atomic force microscope (AFM) provides three-dimensional structure of surfaces at high resolution. Nevertheless, there are some requirements for work with biological specimens which should be taken into consideration in the design of an AFM. And a key requirement is that the AFM should be capable of scanning over relatively large areas. In this paper we introduce an experimental AFM head...
A comparative study of the micro-tribological properties of silicon-based component and octadecyltrichlorosilane (OTS) molecular lubricant film which was prepared on Si(100) substrate, and their adhesive and tribological properties were mainly investigated by AFM/LFM. Meanwhile, the effect of relative humidity and scanning velocity was taken into consideration. The results show that the adhesive force...
This study produces low-temperature poly-silicon (LTPS) film by aluminum induced crystallization (AIC) method on Corning Eagle2000 glass substrate. Through the control of different sputtering power in depositing aluminum film, five kinds of specimens with sputtering power of 100, 200, 400, 800 and 1600 Watts, respectively, are made. Crystal quality, surface morphology, roughness and film residual...
