Memristors (MRs)
are considered promising devices with the enormous
potential to replace complementary metal-oxide-semiconductor (CMOS)
technology, which approaches the scale limit. Efforts to fabricate
MRs-based hybrid materials may result in suitable operating parameters
coupled to high mechanical flexibility and low cost. Metal–organic
frameworks (MOFs) arise as a favorable candidate to cover such demands.
The step-by-step growth of MOFs structures on functionalized surfaces,
called surface-supported metal–organic frameworks (SURMOFs),
opens the possibility for designing new applications in strategic
fields such as electronics, optoelectronics, and energy harvesting.
However, considering the MRs architecture, the typical high porosity
of these hybrid materials may lead to short-circuited devices easily.
In this sense, here, it is reported for the first time the integration
of SURMOF films in rolled-up scalable-functional devices. A freestanding
metallic nanomembrane provides a robust and self-adjusted top mechanical
contact on the SURMOF layer. The electrical characterization reveals
an ambipolar resistive switching mediated by the humidity level with
low-power consumption. The electronic properties are investigated
with density functional theory (DFT) calculations. Furthermore, the
device concept is versatile, compatible with the current parallelism
demands of integration, and transcends the challenge in contacting
SURMOF films for scalable-functional devices.
Surface-Mounted Metal–Organic Frameworks (SURMOFs) growth orientation in [100] or [111] can be deterministically controlled by the SAM chain length, regardless of the surface nature (metallic or insulating).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
