Nano-Characterization

To construct efficient materials at the nanoscale, we must thoroughly understand the way atoms and molecules are arranged.

Our investigations use electron microscopy and spectroscopy to determine the qualities of nanomaterials. By identifying their composition and characteristics, we can gauge their value to a variety of applications. We determine the essential qualities of materials pertinent to nanoscale dimensions and relevant for microelectronics, biomaterials, quantum structures, MEMS devices, organic and quasi-1D devices and thin film materials.

The physical phenomenon of plasmon resonances in small metal particles has been apparent for centuries. They are visible in the vibrant hues of the great stained-glass windows of the world. More recently, plasmon resonances have been used by engineers to develop new, light-activated cancer treatments and to enhance light absorption in photovoltaics and photocatalysis.

Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket. One approach involves designing circuits based on electronic fibers known as carbon nanotubes (CNTs) instead of rigid silicon chips.

But reliability is essential. Most silicon chips are based on a type of circuit design that allows them to function flawlessly even when the device experiences power fluctuations. However, it is much more challenging to do so with CNT circuits.
