Integration of organic based Schottky junctions into crossbar arrays by standard UV lithography

Poly(3-hexylthiophene)/ZnO hybrid pn junctions for microelectronics applications

“…In the inset of the figure, the J-V characteristics of a Au/P3HT/Al Schottky diode with an active area of 20ϫ 20 m 2 is reported for comparison. 16 The P3HT/ZnO junction shows a high rectifying ratio of 10 5 at Ϯ4 V. A remarkable feature is the high current density obtained at 4 V, nearly 10 4 A / cm 2 , which is more than five orders of magnitude higher than in the P3HT device. Moreover, the reverse current is nearly constant up to Ϫ3.5 V and significantly lower than in Al/ZnO/Ag Schottky diodes of Ref.…”

“…16 The junctions were built on a Si n + wafer coated with 100 nm thermal silicon dioxide. Bottom electrodes were fabricated by e-beam assisted evaporation and patterning of a 40 nm thick gold film; a thin Ti layer was first deposited for promoting adhesion.…”

Progress in rectifying-based RRAM passive crossbar array

“…In recent years, organic semiconductors have received considerable attention in the fields of electronic and photonic devices, due to low fabrication cost, low thermal budget requirements, high mechanical flexibility and simple fabricating process compared with the inorganic counterparts [30]. Teo et al [23] fabricated an organic 1D1R device as a write-once-read-many-times memory (WORM).…”

Manufacture and demonstration of organic photovoltaic‐powered electrochromic displays using roll coating methods and printable electrolytes

“…Thin, functional, organic, and polymeric films for electronic devices have attracted significant interest industrially due to the promise of enabling manufacture of equivalents to existing solutions much more efficiently and at much lower cost. Examples of this include organic light emitting diodes (OLEDs),1 white OLEDs2 and light emitting electrochemical cells,3, 4 light harvesting devices such as small molecule photovoltaics5 and polymer photovoltaics (OPVs),6 color changing devices for displays such as e‐paper, LCDs, and electrochromics (ECs),7 logic circuitry such as transistors,8 diodes,9 and memory elements,10 and energy storage devices such as thin film batteries11 and supercapacitors 12. Advantages of the many organic‐based materials discussed above, over their well‐established inorganic counterparts, include processability to yield printable materials, mechanical flexibility to allow use of flexible and organic substrates, and lower power consumption in many cases 13.…”
