Research: Photonic Sintering of Aerosol-Jet-Printed Inorganic Semiconductor Thin Films
Solution processed Inorganic semiconductor materials have broad potential applications in printing electronics due to their high intrinsic carrier mobility and good environmental stability. However, high annealing temperature (350C) and long annealing time (1h) of semiconductor thin film have been the obstacles for fabrication of printed electrolyte gated transistors (EGTs) on flexible substrate. In this project, we applied photonic sintering to anneal the aerosol jet printed inorganic semiconductor thin film at relative low temperature and short annealing time. Photonic sintering achieves fast heating and fast cooling of the film by giving off pulsed intense light. Fast annealing of the printed film can be achieved without doing damage to flexible substrate. We are looking for a suitable inorganic semiconductor for both photonic sintering and aerosol jet printing and exploring a stable way to obtain a dense and homogeneous semiconductor thin film at low temperature

Research: Printed Electronics and Roll-to-Roll UV Micromolding
Printing demonstrates great promise for the fabrication of electronic devices due to its low cost, additive nature, and compatibility with continuous manufacturing. By combining UV-micro imprinting with inkjet printing, our group has increased the resolution and aspect ratio (Height/Width) of printed features through the SCALE process (Self-aligned. Capillarity Assisted Lithography for Electronics). I am currently working on the optimization of a roll-to-roll UV imprinting process for creating micron scale, high aspect ratio features on a plastic web for SCALE as well as the improved fabrication of printed metal conductors through the SCALE process.

Research: Gate-Tunable Electrochemical Devices
Understanding and controlling interfacial electrochemical phenomena is key to optimizing energy conversion and storage devices. In my doctoral research, I work on back-gated electrochemical devices that utilize electrostatic charging (induced by a gate bias) to control electrochemical reactions on two-dimensional materials. By investigating how the band alignment and electronic occupation at the electrode/electrolyte interface affect electrochemical processes, this work will facilitate rational design of electrode materials.

Research: Enhancement of Printed Polymer Electronic Performance
Flexible electronics are nowadays drawing attentions because of their high device density and ability to be integrated into wearable health monitoring systems. To this goal one important step is to fabricate devices on flexible substrates rather than silicon or sapphire, which requires new device structures and materials, namely, new conductors, semiconductors, and dielectrics. Polymers, with their vast and interesting tunable properties, are promising candidates for this application. The goal of this research is to use polymer-based inks to print different electrical devices and circuits including inverters, ring oscillators, etc. Previously, transistors and inverters with good performance were made in the group using ion-gel as the dielectric. Fabricating more complex circuits, enhancing their dynamic and static performances, and developing new printing methods are the research areas I am currently working on.

Research: Organic Electronics
From a fundamental perspective, the goal of molecular electronics is to understand the connection between the molecular structure and the conductivity of molecular wires. We use conducting probe atomic force microscopy (CP-AFM) to contact small numbers of molecules to test their electrical properties. Based on the experimental data, we use a well established analytical model to depict electronic structures of the molecular junction including effective energy offset for charge transport and moelcule-electrode coupling. We are looking for an efficient method to captures the essential transport physics in these systems.
