Micro- and nanostructures are the foundations of microelectronics and nanotechnology. We are interested in developing high-resolution, low-cost and high-throughput patterning techniques for the creation of ordered micro- and nanostructures. Particularly, we are interested in developing new concepts, schemes and equipment for advanced photolithography and nanoimprint techniques.
In the devices area, we work on the fabrication and characterization of novelelectronic and photonic devices, and solid-state sensors and actuators. In addition to traditional silicon and compound semiconductors, we are interested in integrating novel materials such as organic semiconductors and chalcogenidesin electronic and M/NEMS devices. However, many devices based on new materials suffer poor performance. For example, current organic transistors have low cutoff frequency and poor uniformity, which greatly limit their usefulness in circuit applications. We are working on using unconventional device architectures to circumvent performance-limiting factors.
Microelectronic and M/NEMS devices are particularly useful when they are integrated into complex systems. Integrated Macroelectronics (IM) are large-area integrated systems formed by two-dimensional arrays of microelectronic and M/NEMS devices and sensors on rigid or flexible substrates. Each element in the array is individually controlled and accessed by a passive-matrix or an active-matrix circuitry. Typical examples of IM include flat-panel displays and sensor arrays for X-ray and infrared imaging. By using different types of microelectronic sensors and M/NEMS transducers and actuators at each pixel, advanced applications such as digital biochip experimental platform and flexible artificial skin can be realized. We are interested in developing transformative IM systems through disruptive innovation for applications in flat-panel display, metrology and imaging, micro/nano fabrication, bioengineering and artificial skin.
