Abstract
An apparatus for installing and operation single align nanometer structure material is consisted of subpanel, axial adjusting bar, and differential agent. A guidance pipe of axial adjusting bar is fixed at one side of subpanel and differential agent is fixed at the other side; one end of axial adjusting bar is linked to differential agent while another one is linked by insulating sleeve joint to a jiont whereon a needle shaped electron is install to match it, another needle shaped electron is installed on the top of pipe, and the two needle shaped electrons have their top coaxial opposed. The distance of two needle shaped electrons can be adjusted through pipe and axial adjusting bar which air-tight seal cooperates with subpanel. The device has needle shaped electron as fixed point of fixed point of single align nanometer structure material, benefiting for observation and measurement to sample with transmission electron microscope, supplying convenience for researcher impressing varies of experimental electric signal, and satisfying installation condition of transmission electron microscope by air-tight seal connecting each part.
