Journal ArticleDOI
Role of gallium doping in dramatically lowering amorphous-oxide processing temperatures for solution-derived indium zinc oxide thin-film transistors
TL;DR: This work results in a new generation of high-performance liquid chromatography beads that are able to withstand high-temperature conditions and have low viscosity at low temperatures.
Journal ArticleDOI
Transparent active matrix organic light-emitting diode displays driven by nanowire transistor circuitry.
Sanghyun Ju,Jianfeng Li,Jun Liu,Po-Chiang Chen,Young-Geun Ha,Fumiaki Ishikawa,Hsiao-Kang Chang,Chongwu Zhou,Antonio Facchetti,David B. Janes,Tobin J. Marks +10 more
TL;DR: The first demonstration of AMOLED displays driven exclusively by NW electronics are reported and it is shown that such displays can be optically transparent.
Journal ArticleDOI
High-performance solution-processed amorphous zinc-indium-tin oxide thin-film transistors.
Myung-Gil Kim,Hyun Sung Kim,Young-Geun Ha,Jiaqing He,Mercouri G. Kanatzidis,Antonio Facchetti,Tobin J. Marks +6 more
TL;DR: It is shown that structural relaxation and densification by In(3+) and Sn(4+) mixing is effective in reducing carrier trap sites and in creating carrier-generating oxygen vacancies.
Journal ArticleDOI
Printable cross-linked polymer blend dielectrics. Design strategies, synthesis, microstructures, and electrical properties, with organic field-effect transistors as testbeds
TL;DR: The synthesis and dielectric properties of optimized, cross-linked polymer blend (CPB) dielectrics for application in organic field-effect transistors (OFETs) are reported and the CPB film quality is correlated with the PVP-cross-linking reagent reactivity.
Journal ArticleDOI
Flexible Low-Voltage Organic Thin-Film Transistors Enabled by Low-Temperature, Ambient Solution-Processable Inorganic/Organic Hybrid Gate Dielectrics
Young-Geun Ha,Sunho Jeong,Jinsong Wu,Myung-Gil Kim,Vinayak P. Dravid,Antonio Facchetti,Tobin J. Marks +6 more
TL;DR: The morphologies and microstructures of representative semiconductor films grown on CHB dielectrics prepared with incrementally varied compositions and processing conditions are investigated and shown to correlate closely with the OTFT response.
