Abstract
This lecture focuses on the challenging design and realization of new materials for creating unconventional electronic structures, illustrating with two topics. The first part deals with methods to achieve high-throughput printing of electronic circuitry. Materials design topics include: 1) Rationally designed high-mobility p- and n-type organic semiconductors for printed organic CMOS, 2) Polycrystalline and amorphous oxide semiconductors for transparent and mechanically flexible electronics, 3) Self-assembled high-k nanodielectrics enabling ultra-large capacitance, low leakage, high breakdown fields, minimal trapped interfacial charge, and radiation hardness, 4) Combining these materials sets to fabricate high-performance thin-film transistor-based devices.
The second topic deals with organic solar cells and the challenge of molecularly tailored interfaces to modulate charge transport across hard matter-soft matter interfaces. Such interfacial tailoring can also control carrier-trapping defects at such interfaces and stabilize them with respect to physical/thermal decohesion. Challenges and opportunities are illustrated in: 1) charge transport across hard matter-soft matter interfaces in electroluminescent devices, 2) charge transport across hard matter-soft matter interfaces in organic photovoltaic cells, 3) charge transport to unconventional electrodes. Interface engineering along with improved bulk-heterojunction polymers yields plastic solar cells with efficiencies as high as 5.6% - 7.6%, along with greater cell durability.
