a r t i c l e i n f o Thin-films and organic field-effect transistors fabricated from a solution-processable precursor of zinc tetra-benzoporphyrin (ZnTBP) are reported. Amorphous, insulating precursor films were deposited by spin-casting and thermally converted into polycrystalline, semiconducting thin-films comprising grains on the order of 5 μm in diameter. Thin-film X-ray diffraction indica...

Recent rapid advancement in antiferromagnetic spintronics paves a new path for efficient computing with THz operation. To date, major studies have been performed conventional metallic, e.g., Ir-Mn and Pt-Mn, semiconducting, CuMnAs, antiferromagnets, which may suffer from their elemental criticality high resistivity. In order to resolve these obstacles, films are under intense development device...

Lamellar nanocomposites based on semiconducting polymers incorporated into layered inorganic matrices are prepared by the co-assembly of organic and inorganic precursors. Semiconducting polymer-incorporated silica is prepared by introducing the semiconducting polymers into a tetrahydrofuran (THF)/water homogeneous sol solution containing silica precursor species and a surface-active agent. Semi...

sno nanoparticles were synthesized using microwave–assisted hydrothermal method. it was noticed that at 300 and 600 watt microwave power, sno formed and remained in the tetragonal phase. at 900 watt, sno2 started appearing and a mixture of sno and sno2 phases coexisted. the particle size varied from ~2 to ~13 nm at 300 to 900 watt radiation power. the uv-v absorption spectra showed the excitoni...

The ultrafast spectroscopy of single domains of polycrystalline films of TIPS-pentacene, a small-molecule organic semiconductor of interest in electronic and photovoltaic applications, is investigated using transient absorption microscopy. Individual domains are distinguished by their different polarization-dependent linear and nonlinear optical responses. As compared to bulk measurements, we s...

The generally accepted view that spin polarization in non-magnetic solids is induced by the asymmetry of the global crystal space group has limited the search for spintronics materials mainly to non-centrosymmetric materials. In recent times it has been suggested that spin polarization originates fundamentally from local atomic site asymmetries and therefore centrosymmetric materials may exhibi...

We report the capacitance-voltage (C-V) measurements on thin-film transistors (TFTs) using solution-processed semiconducting carbon nanotube networks with different densities and channel lengths. From the measured C-V characteristics, gate capacitance and field-effect mobility (up to ~50 cm(2) V(-1) s(-1)) of the TFTs were evaluated with better precision compared with the results obtained from ...

A new oligomer of bithiophene and substituted fluorene has been successfully synthesized, exhibiting good FET performance. Our results show that devices can be obtained from inkjetted OTFTs and elaborated by direct writing without any particular pre-patterning or self-alignment techniques. We have also demonstrated the possibility to fabricate inexpensive OTFTs by direct writing paving the way ...

Abstract Two-terminal ferroelectric synaptic weights are fabricated on silicon. The active layers consist of a 2 nm thick WO x film and 2.7 HfZrO 4 (HZO) grown by atomic layer deposition. ultra-thin HZO is crystallized in the phase using millisecond flash at temperature only 500 °C, evidenced x-rays diffraction electron microscopy. current density increased four orders magnitude compared to bas...

Abstract The p-type characteristic of solution-processed metal halide perovskite transistors means that they could be used in combination with their n-type counterparts, such as indium–gallium–zinc-oxide transistors, to create complementary metal–oxide–semiconductor-like circuits. However, the performance and stability perovskite-based do not yet match which limit broader application. Here we r...
