Progress in synthetic strategies over the last two decades has allowed precise control on morphology and stoichiometry, enabling the development of i.e., nanoparticles, nanosheets, nanorods and thin films with thickness in nanometres. A variety of fabrication techniques-including hydrothermal/solvothermal methods, chemical vapor deposition, electrodeposition, and ion-exchange processes-have been extensively applied to obtain nickel telluride with tailored properties. To understand structural, electronic, and physico-chemical characteristics, researchers has opted for characterization of nickel telluride(s) by various spectroscopic and electro-analytical techniques such as X-ray analysis, Raman spectroscopy, transmission electron microscopy. Due to their excellent electrical conductivity (950 mSm⁻¹), thermal conductivity (2.5 Wm⁻¹K⁻¹) intrinsic chemical robustness, and catalytic efficiency, nickel tellurides have demonstrated potential across multiple domains. Nevertheless, challenges such as phase purity (hexagonal and trigonal), stability of their shape and size vis-a-vis commercial viability still hinder their widespread utility.

In this work, the SCLC technique to accurately determine the mobility of holes and electrons in organic semiconductors is investigated in detail. Recognizing the importance of balanced charge transport to the performance of optical and electronic devices, the fundamentals of SCLC, including Mott-Gurney's law, are discussed and its advantages over alternative methods are highlighted. A carbazole-based compound is used as a practical example, with single-carrier devices fabricated to selectively measure hole-only and electron-only transport.
