Synthesis and Properties of Nano-materials

Brongersma's research focuses on the fabrication and characterization of nanometer-size electronic and optical devices. The ability to engineer materials at the atomic level has opened myriad possibilities for the advancement of technologies that impact the areas of semiconductors, telecommunications, chemistry, and pharmaceuticals. His current research is aimed at the development of Si-based microphotonic functionality and plasmonic devices that can manipulate the flow of light at the nanoscale.

Clemens studies the growth, structure, magnetic properties, and mechanical properties of thin films and nanostructured materials. By controlling growth and atomic scale structure, he is able to tune and optimize properties. He is currently investigating materials for metallization, magnetic recording, electronic device, and hydrogen storage applications.

Research Interests include nanocrystal and nanowire synthesis and self-assembly, electron transfer and transport in nanomaterials and at the nanointerface, nanoscale electronic and photonic devices, batteries, solar cells, microbial fuel cells, water filters and chemical and biological sensors.

The research of my group interfaces with chemistry, physics, materials science, and biological and medical science. We are interested in solid state and soft biological materials that have well-defined atomic structures. Our work is in the areas of materials chemistry, solid state chemistry and physics, scanning probe microscopy, molecular electronics, novel chemical and biochemical sensors and nanomaterial based biological transporters and carriers for drug, DNA and protein delivery and novel therapeutics applications of nanomaterials.

Heilshorn's interests include biomaterials in regenerative medicine, engineered proteins with novel assembly properties, microfluidics and photolithography of proteins, and synthesis of materials to influence stem cell differentiation. Current projects include creating in vitro circuits of neurons, tissue engineering for spinal cord regeneration, and designing scaffolds for cell transplantation in the treatment of Parkinson's disease and stroke.

Dr. Kelly is a consulting Professor in the Department of Materials Science and Engineering at Stanford. He has over 30 years experience in developing sensors and spectroscopic instruments used to study a wide variety of organic and inorganic surface phenomena. He has published widely, and holds numerous patents in the fields of electron optics, thin film synthesis, and electron spectrometers. He will participate in the CCNE-TR program by assisting in the development of biosensors, and by evaluating their performance using X-ray photoelectron spectroscopy, secondary ion mass spectrometry, and other surface sensitive techniques.

Lindenberg's research is focused on probing the ultrafast dynamics and atomic-scale structure of materials on femtosecond and picosecond time-scales. X-ray techniques are combined with ultrafast laser techniques to provide a new way of taking snapshots of materials in motion. Current research is focused on the dynamics of phase transitions, ultrafast properties of nanoscale materials, photoelectrochemical charge transfer dynamics, and THz nonlinear spectroscopy.

McIntyre’s group performs research on nanostructured inorganic materials for applications in electronics, energy technologies and sensors.  He is best known for his work on metal oxide/semiconductor interfaces, ultrathin dielectrics, defects in complex metal oxide thin films, and nanostructured Si-Ge single crystals.  His research team synthesizes materials, characterizes their structures and compositions with a variety of advanced microscopies and spectroscopies, studies the passivation of their interfaces, and measures functional properties of devices.

Melosh's research is focused on developing methods to detect and control chemical processes on the nanoscale, to create materials that are responsive to their local environment. The research goal incorporates many of the hallmarks of biological adaptability, based on feedback control between cellular receptors and protein expression. Similar artificial networks may be achieved by fabricating arrays of nanoscale (<100 nm) devices that can detect and influence their local surroundings through ionic potential, temperature, mechanical motion, capacitance, or electrochemistry. These devices are particularly suited as 'smart' biomaterials, where multiple surface-cell interactions must be monitored and adjusted simultaneously for optimal cell adhesion and growth. Other interests include precise control over self-assembled materials, and potential methods to monitor the diagnostics of complicated chemical systems, such as the effect of drug treatments within patients.

The Salleo Research Group is interested in novel materials and processing techniques for large-area and flexible electronic/photonic devices as well as ultra-fast laser processing for electronics, photonics and biotechnology. We also study defects and structure/property relations of polymeric semiconductors, nano-structured and amorphous materials in thin films.

Wang is engaged in the research of magnetic nanotechnology, biosensors, spintronics, integrated inductors and information storage. He uses modern thin-film growth techniques and lithography to engineer new electromagnetic materials and devices and to study their behavior at nanoscale and at very high frequencies. His group is investigating magnetic nanoparticles, high saturation soft magnetic materials, giant magnetoresistance spin valves, magnetic tunnel junctions, and spin electronic materials, with applications in cancer nanotechnology, in vitro diagnostics, rapid radiation triage, spin-based information processing, efficient energy conversion and storage, and extremely high-density magnetic recording.
