title: 3D nanostructural properties of heterogenic materials
reg no: ETF5545
project type: Estonian Science Foundation research grant
subject: 1.1-1.5. Exact Sciences
status: completed
institution: Institute of Physics at University of Tartu
head of project: Ilmar Kink
duration: 01.01.2003 - 31.12.2004
description: The goals of the project are:
1. Development of a novel method for highly accurate (down to atomic resolution) determination of a spatial structure of solid materials. The method combines the Scanning Probe Microscopy with a technology that enables consecutive removal of surface layers. Compared to existing technologies it can measure the structure at orders of magnitude higher accuracy (vs x-ray tomography) and can be applied in the case of non-homogenous materials (vs x-ray crystallography). The method enables to study on a fundamental level distribution of components and its influence of properties of different composite materials; origins and distributions of defects and irregularities and their impact on material properties; nanostructures, e.g. quantum dots and their properties depending on the spatial distribution.
2. In collaboration with different groups determine nanostructure of several heterogeneous specimen:
a) the nature and distribution of surface and subsurface defects, and distribution of components of Ti and Wf compounds for nanotribological investigations
b) structure of heterogeneous ceramic matarials with complicated structures (e.g. high temperature superconductors).
c) Structural transitions of multistructural semi-conductors and their influences on properties of the materials
d) Dependence of the immobilization of large protein molecules (e.g. DNA) on a nanostructure of the carrier surface
