Nanoscale Electronics, Photonics and Materials Processing

Under the umbrella of Nanoscale Electronics, Photonics and Materials Processing, many research groups within CBE are at the forefront of research in areas such as materials properties in nanofibers, energy harvesting efficiency of solar cells using photonic crystals, and surface science of organic and inorganic materials.

The research conducted in these areas has a direct impact on:

  • Processing and design of next-generation electronic materials for logic gates, memory, and interconnects.
  • Fabrication and device integration of nanoscale building blocks for solar cells and next-generation lithium ion batteries.
  • Organic and inorganic materials for solid-state lighting, LEDs, and computer displays.
  • Organic semiconductor materials for large-area flexible displays.

Research Foci of Faculty in Nanoscale Electronics, Photonics, and Materials Processing
Prof. Lynden Archer's research is rooted in nanoscale materials. His group investigates how these materials behave at the fundamental level, as well as applying them to electrochemical energy storage (batteries). The materials studied most extensively are called Nanoscale Organic Hybrid Materials (NOHMs), which are created by attaching polymers to the surfaces of nanoparticles.  

Prof. Paulette Clancy's laboratory is one of the leading groups in the country studying atomic- and molecular-scale modeling of semiconductor materials. Her team focuses on prediction and insight regarding the link between material design and properties, allowing them to suggest processing conditions and tailored materials to fulfill a desired set of constraints. Her primary current foci are novel materials for (1) photovoltaic applications for solar cells and (2) laser annealing of semiconductors and porous low-k materials. 

Prof. James Engstrom's group focuses in three areas: controlling thin film nucleation in nanoscale electronics using techniques such as atomic layer deposition; organic thin film electronics, using in situ real time X-ray synchrotron radiation; and modification and processing of inorganic nanocrystalline materials. 

Prof. Fernando Escobedo's research group is at the forefront of contributors to novel methods for the simulation of both thermodynamic data (like free-energies and microstructure) and kinetic information (like transition mechanisms and rate constants) from molecular-level models of complex materials. His current interests center on understanding structure-property relationships for polymeric and colloidal materials. The ultimate goal of generating such new fundamental knowledge is to improve the engineering of materials of desirable or "super" properties that originate in the creation of special types of structural order or the control of phase transitions. 

Prof. Tobias Hanrath's research efforts focus on the fundamental study of optoelectronic properties of semiconductor nanocrystals; this work is inspired by the potential application of these materials in solar energy conversion and energy storage devices. The semiconductor nanocrystals used in his work provide a diverse set of building blocks whose electronic and optical properties differ from their bulk counterparts due to the spatial wavefunction confinement. 

Prof. Yong Joo's research focuses on the integration of molecular details into a macroscopic level in polymeric materials processing. Areas of current interest include the microstructural rheology and processing of complex fluids, the formation of nanostructures in nanofibers, and the occurrence of viscoelastic instabilities in polymer flows. His group has laid the new foundation for experimental and theoretical studies on advanced, scalable manufacturing processes based on the flow instability such as gas-assisted electrospinning and Taylor-Couette (T-C) reactors with axial flow. Incorporation of high loading of inorganic precursors into water-soluble polymers in gas-assisted electrospinning gave rise to cost-effective, facile production of metallic and ceramic nanofibers.

Prof. Donald Koch's group studies the rheology and average transport in particle suspensions, porous media, micro- and nano-structured materials. Some examples of studies focused on materials and their properties are: particle-filled polymeric materials, solvent-free nanoparticle fluids, and aggregation processes in colloids and aerosols. 

Prof. Paul Steen is an expert in the stability of liquid/ gas interfaces, flows driven by capillary action, and fluid dynamics of planar flow spin casting. In particular, his group studies heat flow in planar-flow spin casting, a process by which molten metals are rapidly solidified into thin sheets; of importance in the manufacturing of new metallic glassy materials for application in ultra-efficient solid-state energy conversion devices. 

Prof. Abraham Stroock's lab focuses on manipulating dynamics and chemical processes on micrometer scales. Current efforts in the lab related to materials are: (1) the study and application of mechanisms for manipulating liquids inspired by plants, (2) fundamental studies in the properties of liquid water at negative pressure, (3) studies of the biophysical processes that control vascular development and applications of these processes in tissue engineering, and (4) theoretical, numerical, and experimental studies of fluid mechanical processes on small scales for chemical process.
