Abstract
Methods of determining the length of nanowires and/or carbon nanotubes (CNTs), as well as systems for performing the same are provided. The methods and systems include the use of passing a polarized light beam through a sample container that is situated between parallel plate electrodes and subjected to a varying electric field. Measurement of the dichroism amplitude in the sample allows for the determination of nanowire and/or CNT lengths in the sample.
Claims21
A method of measuring nanowire or carbon nanotube (CNT) lengths, the method comprising:
- illuminating a sample comprising a plurality of nanowires or CNTs with a polarized laser light source;
- applying an electric potential to the sample with a plurality of electrodes;
- and
- monitoring the sample dichroism amplitude as a function of the electric potential and direction of the polarized laser light to determine the nanowire or CNT lengths in the sample.
A system for measuring nanowire or carbon nanotube (CNT) length, comprising:
- a laser light source;
- a first polarizer;
- a plurality of electrodes;
- a sample container through which the laser light passes;
- and
- a detector to detect the dichroism amplitude of light passing through the sample container.
