The deepness enhancing of an AFM-tip induced surface nanomodification
The novel method of the semiconductor nanostructuring (TINE&MEMO) has been developed on the base of the simultaneous AFM-tip induced local anodic oxidation and mechanical modification of the surface under the applying of advanced electric potentials. The TINE&MEMO-based technology allows obtaining the principle new scale of the depth up to 100 nm for the nanostructure fabrication with a low asp...
متن کاملTip and surface properties from the distance dependence of tip–surface interactions
Macroscopic “background” interactions, such as van der Waals and electrostatic forces, determine the frequency change in non-contact atomic force microscopy (NCAFM). We demonstrate that by analysing the distance dependence of these interactions one can extract more information about the tip radius, charge and chemical composition, as well as about the surface charging and conductivity. For this...
متن کاملThe role of tip size and orientation, tip-surface relaxations and surface impurities in simultaneous AFM and STM studies on the TiO2(110) surface.
In this work we investigate some of the key factors in simultaneously recorded scanning tunneling microscopy (STM) and non-contact atomic force microscopy (nc-AFM) images of the TiO(2)(110) surface, particularly the role of tip size and orientation in the obtained contrast pattern, and the importance of tip-surface relaxations and surface impurities in measured currents. We show that, while usi...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
