I really enjoyed my summer research internship with the Loo Group at Princeton University. My project involved using an inkjet printer to deposit carbon nanotubes onto preprocessed silicon wafers to make simple electronic devices (Field Effect Transistors). This technique is scalable to industrial levels of production and it offers precise control over the location and quantity of deposited material. As such, cost, materials, and energy consumption as well as the environmental impact of production can all be greatly reduced. This in turn would likely make technology cheaper and more accessible and thus address the world’s energy challenge. I spent the majority of my internship perfecting the preparation and dispensation of the “carbon nanotube ink” in order to achieve working devices. I learned how to construct and conduct systematic studies, how to troubleshoot effectively, and how to sift through various books and research papers to obtain specific relevant information. This internship stimulated and sharpened my interest in doing research at a higher level while allowing me to work in a friendly yet challenging environment. I would definitely recommend future internships with the Loo research group and I will use this invaluable experience in looking towards graduate school.
