research picture 1 Nano Fiber Foam
Currently we are able to grow graphite on patterned metal structures at ~500 Celsius. Efforts are currently towards lowering this deposition tempearature and implementing the graphitic structures into electrical interconnects and ICs.

research picture 2 In-situ studies of the mechanical properties of thin films:
As the surface area to volume ratio of a material increases its material properties may begin to change, possibly in a drastic manner. Currently we are studying thin (100 nm or less in thickness) Au films and find some remarkable behavior.

research picture 3 Stiction (Adhesion) Preventionin Nano/Microdevices:
A consequence of the decreased dimensions of nano/micro devices is that "secondary" forces become more dominant than gravity. This causes many devices to fail prematurely either by adhering to their substrate or neighboring structures. Currently we are styudying the energy associated with creating new surfaces by the so calle peel tests, in which a failed device is peeled of from a substrate. We are exploring the use of structural vibrations for prevention and repair of stiction failure. The methods invovled are easily applicable to other complex MEMS structures/devices by simple modifications.

research picture 4 Growth of Aligned Arrays of Single Walled Carbon Nanotubes:
Current efforts are toward creation of a SWNT field effect transistor where a major stumbling block has been growth of aligned arrays of SWNTs. Recently we have been able to grow SWNT of 1 – 1.3 nm diameter in aligned arrays with ~ 2 nm spacings.

research picture 5 Phononic Crystals
We have simulated, tested and charactrized Phononic Crystals operating at super high frequency and EHF. Currently we are fabricating these meta-materials operating at 33GHz. Experimentally we are measuring the thermal conductivity and phononic bandgap for elastic waves to theoritically study these materials, and we are performing FEA, FDTD and PWE. This research is aimed to fabricate high Q factor mechanical resonator, improved the current limits of different material properties and enter the quantum field regime.
