Raman Identification of Polymorphs in Pentacene Films

Crystals, 2016
We use Raman spectroscopy to characterize thin films of pentacene grown on Si/SiO x by Supersonic Molecular Beam Deposition (SuMBD). We find that films up to a thickness of about 781 Å (∼ 52 monolayers) all belong to the so-called thin-film (TF ...

Thermally Stable Organic Synaptic Transistors Using a High‐Tg Polymer Electret

Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.
A high–glass‐transition‐temperature cyclic olefin copolymer (COC) electret enables thermally stable organic synaptic transistors for neuromorphic operation in harsh environments. UV–ozone treatment increases the trap density in COC, providing robust multilevel conductance and key synaptic functions (excitatory postsynaptic current/ inhibitory ...

Single-Walled Carbon-Nanotubes-Based Organic Memory Structures

Molecules, 2016
The electrical behaviour of organic memory structures, based on single-walled carbon-nanotubes (SWCNTs), metal–insulator–semiconductor (MIS) and thin film transistor (TFT) structures, using poly(methyl methacrylate) (PMMA) as the gate dielectric, are ...

Efficient Energy Transfer and Singlet Fission in Co‐Deposited Thin Films of Pentacene and Anthradithiophene

Advanced Materials Interfaces
Co‐deposited molecular heterostructures with statistical intermixing of the constituents are attractive candidates to tune the optical and the transport properties, as well as the ability to promote photophysical processes like singlet fission.

Multi-domain gate-engineered pentacene OFET for hydrogen detection: design, modeling, and simulation

Nano Express
This research work addresses key challenges in organic field-effect transistor (OFET)-based gas sensors by proposing a compact differential hydrogen ( $\textrm{H}_2$ ) sensor based on a pentacene OFET with a bottom gate extended in both in-plane and out ...

Acid-Mediated Dimerization of TIPS-Pentacene

The Journal of Organic Chemistry
TIPS-pentacene (TIPS-Pc), a benchmark organic semiconductor, is shown to undergo acid induced dimerization upon treatment with strong Brønsted acids such as trifluoroacetic acid (TFA). Mechanistic studies indicate that some acids oxidize the pentacene core to form a radical cation, which then engages a second neutral TIPS-Pc molecule in a radical ...
