Here, we demonstrate an organic donor/acceptor (D/A) heterostructure-based diode rectifier fabricated with thin films of Copper phthalocyanine/7,7,8,8-Tetracyanoquinodimethane (CuPc/TCNQ). The D/A materials were deposited in a hybrid way; with CuPc film being deposited by solution processing, while TCNQ film was thermally evaporated under vacuum conditions. The diode exhibited excellent electrical stability, reproducibility, and achieved a rectification ratio (RR) greater than 10<sup>3</sup> at 1.2 V. A low threshold voltage ca. 0.4 V and an ideality factor of 2.3 could be achieved from the diode characteristics. Moreover, with the variation in thickness of TCNQ film, the electrical characteristics of the diode changed drastically, offering a good way to enabling fine-tuning of device characteristics, including, turn-on voltage, leakage current, and overall rectification efficiency. An optimum film thickness of TCNQ (320 nm) with fixed CuPc film thickness (330 nm) has been identified for best device performances. The device produced a steady DC response under varying sinusoidal pulses with a frequency response about 1 MHz, making it suitable for radio frequency identification (RFID) applications. Additionally, CuPC/TCNQ heterostructure was integrated on flexible substrate for promising diode characteristics.</p>\u0000 </div>","PeriodicalId":146,"journal":{"name":"ChemistrySelect","volume":"11 13","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147585156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finite elements based couples thermo-mechanical simulation is conducted elements in COMSOL Multiphysics to inspect thermal conduction, temperature variations, structural changes, and the generation of stress during the operation of gas turbines. The comparative study reveals that the inclusion of niobium markedly enhances the thermal characteristics of the alloy. The AISI 403 + Nb blade exhibits a more consistent temperature distribution and diminished thermal gradients, resulting in decreased thermal stresses and enhanced structural integrity. Furthermore, the overall deformation is less than that of standard AISI 403, indicating improved durability against thermo-mechanical loading.
