Abstract An experimental detail on the morphology engineering and characterizations of all-inorganic Sn-based perovskite (here CsSnI 3 ) thin films their application in photodetectors are presented. In particular, we demonstrated that chlorobenzene anti-solvent treatment during thin-film spin coating could effectively optimize properties obtained film. SEM AFM measurements showed uniform film w...

The pick-up-stick transistor concept is demonstrated using materials that are both air-stable and fully solution processable. In this paper, the thin film transistor (TFT) semiconductor is a bilayer structure with an array of carbon nanotubes (CNTs) as an underlayer and an alkyl-substituted hexabenzocoronene (HBC) overcoat. Electrical current flowing through the structure favors the low resista...

The high field properties of carbon nanotube (CNT) network thin film transistors (CN-TFTs) are important for their practical operation, and for understanding their reliability. Using a combination of experimental and computational techniques we show how the channel geometry (length L(C) and width W(C)) and network morphology (average CNT length L(t) and alignment angle distribution θ) affect he...

We report hysteresis-free carbon nanotube thin-film transistors (CNT-TFTs) employing a fluorocarbon polymer (Teflon-AF) as an encapsulation layer. Such fluorocarbon encapsulation improves device uniformity with excellent operation stability in air and even in water. The fluoropolymers possess high hydrophobicity for efficient removal of water molecules from the vicinity of nanotubes, which are ...

Graphitized multiwalled CNTs (carbon nanotubes) were purchased from ECHO Chemical Co. Ltd. (Taiwan) with an external diameter of 2040 nm and a length of 0.5200 m. The raw CNT powder was etched in 15 M boiling nitric acid solution for 1h. The CNTs were then washed several times with de-ionized water until the pH value of the solution became neutral. Nickel hydroxide nanonets were grown on the...

We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...

In this paper, we model the evolution and self-assembly of randomly oriented carbon nanotubes (CNTs), grown on a metallic substrate in the form of a thin film for field emission under diode configuration. Despite high output, the current in such a thin film device often decays drastically. The present paper is focused on understanding this problem. A systematic, multiphysics based modelling app...

BACKGROUND Nanomedicine has the potential to revolutionize medicine and help clinicians to treat cardiovascular disease through the improvement of stents. Advanced nanomaterials and tools for monitoring cell-material interactions will aid in inhibiting stent thrombosis. Although titanium boron nitride (TiBN), titanium diboride, and carbon nanotube (CNT) thin films are emerging materials in the ...

Using an atomic force microscope (AFM) at a controlled contact force, we report the electrical signal response of multi-walled carbon nanotubes (MWCNTs) disposed on a golden thin film. In this investigation, we highlight first the theoretical calculation of the contact resistance between two types of conductive tips (metal-coated and doped diamond-coated), individual MWCNTs and golden substrate...
