20 megahertz operation of organic nanodiodes

Abstract

Solution-processed polymer nanodiodes operating at frequencies up to 20 MHz are demonstrated. As the active layer, p-type semiconductor poly(didodecylquarterthiophene) (PQT12) was used. It is shown that devices based on linear arrays of semiconducting polymer nanowires with intentionally broken symmetry display nonlinear current-voltage characteristics similar to conventional diodes. The so-called self-switching devices (SSDs) are single layered, planar structures that can be easily fabricated in a single step of nanolithography. The SSDs possess substantially lower parasitic capacitance between contacts than conventional organic diodes and organic thin-film transistors, and we show that the nano-rectifiers can operate at frequencies well above both 125/134 kHz and 13.56 MHz RFID communication bands.

High electrical conductivity and carrier mobility in oCVD PEDOT thin films by engineered crystallization and acid treatment

“…The performance of this rectifier satisfies the standard frequency of 13.56 MHz for the HF system (33). It is also among the best-performing organic rectifiers (33,34) in terms of working frequency and outperforms many other organic rectifiers with similar structures (33). In summary, this study demonstrates record-high electrical conductivity of PEDOT with engineered crystallization and morphology.…”

Graphene bridge rectifier based on self-switching diode arrays

“…OUT OUT is plotted as a function of input current. This also changes quadratically with the input current, as is predicted by equation (7). , where V G is the gate voltage offset from the neutrality point.…”

“…Since then, there have been experiments showing their capability to operate at room temperature at high frequencies, up to and including terahertz (THz) [3]. They have been operated as microwave and THz detectors [4][5][6], and fabricated in other materials such as GaN [5], organic polymer [7], and zinc-oxide thin films [8]. SSDs fabricated from graphene (also known as graphene SSDs, GSSDs) have also been demonstrated [6,9,10], modelled [11], and simulated [12,13].…”
