Print Transferrable Large-Area Broadband Membrane Reflectors by Laser Interference Lithography

Seo J.-H., Park J., Zhao D., Yang H., Zhou W., Ju B.K., Ma Z., University of Wisconsin-Madison, US

Large-area broadband reflectors based on photonic crystals can enable a number of optoelectronic and photonics devices. To create nano patterns, nanoimprinting, electron-beam lithography and focused ion beam patterning techniques are commonly used. However, these methods [...]

Highly sensitive organic-inorganic heterojunction flexible photodetectors

Seo J.-H., Oh T.Y., Park J., Zhou W., Ju B.K., Ma Z., University of Wisconsin-Madison, US

Heterostructures formed between inorganic and organic materials could lead to many unique device applications due to their unique physical properties, such as mechanical flexibility, large area, low temperature processability and high performance. Since most n-type [...]

Flexible Graphene Transistors via Printing Transfer

Chang T.-C., Suh H.-S., Mikael S., Seo J.-H., Nealey P.F., Ma Z., University of Wisconsin-Madison, US

Graphene is an atomic layer material with the characteristics of high mobility, high mechanical strength, transparency and low injection energy barrier with different work function metals. Good transparent electrodes and flexible graphene-based large scale touch [...]
