“…Table 2 shows the structure parameters of CuPc films. The full width at half maximum (FWHM) intensity of preferential orientation reduced with increasing annealing temperatures, which represents better lattice quality [15], and the crystallite size was estimated from Scherrer's equation [16].…”

In the present paper, Copper Phthalocyanine (CuPc) thin films were deposited on glass and silicon substrate by thermal evaporation and pulsed laser deposition (PLD) methods. CuPc thin films prepared at different annealing temperatures (298, 323, 348, 373, 423 K) respectively. The structure and surface morphology of CuPc in powder and thin films forms prepared by two methods were studied using Energy dispersive X-ray (EDX), X-ray florescence (XRF), X-ray diffraction (XRD), Atomic force microscope (AFM), and Scanning electron microscope (SEM). It showed that there was a change and enhancement in the crystallinity and surface morphology due to change in the annealing temperature (Ta). The purpose of our work is to find the optimal temperature for which the film produces best structural properties for CuPc thin film to produce organic field effect transistor. Analysis of X-ray diffraction patterns of CuPc in powder form showed that it had an α-polycrystalline phase with monoclinic structure, with preferentially oriented (100) plane transform to β-single crystalline morestable structure at different annealing temperatures.

“…Copper phthalocyamine (CuPc) and fluorinated copper phthalocyanine (F 16 CuPc) are widely studied p-type and n-type small-molecule semiconductors for OFETs because of their good carrier mobility and environmental stability. CuPc and F 16 CuPc exhibit a weak dependence of µ sat on temperature around room temperature, each having an E a of 73 and 39 meV [57,58], respectively, which are similar to that of pentacene [55,56]. Therefore, I DS in the saturation region of OFETs based on these materials would also be weakly dependent on temperature and not suitable as the signal output of temperature sensors around room temperature.…”

The rapid growth of wearable electronics, Internet of Things, smart packaging, and advanced healthcare technologies demand a large number of flexible, thin, lightweight, and ultralow-cost sensors. The accurate and precise determination of temperature in a narrow range (~0–50 °C) around ambient temperatures and near-body temperatures is critical for most of these applications. Temperature sensors based on organic field-effect transistors (OFETs) have the advantages of low manufacturing cost, excellent mechanical flexibility, easy integration with other devices, low cross-sensitivity, and multi-stimuli detectability and, therefore, are very suitable for the above applications. This article provides a timely overview of research progress in the development of OFET-based temperature sensors. First, the working mechanism of OFETs, the fundamental theories of charge transport in organic semiconductors, and common types of OFET temperature sensors based on the sensing element are briefly introduced. Next, notable advances in the development of OFET temperature sensors using small-molecule and polymer semiconductors are discussed separately. Finally, the progress of OFET temperature sensors is summarized, and the challenges associated with OFET temperature sensors and the perspectives of research directions in this field are presented.
