Key Properties of Nanomaterials for Electronics Applications

Abstract

Nanomaterials, characterized by at least one dimension within the nanometer scale (1–100 nm), have transformed contemporary electronics due to their distinctive electrical, optical, thermal, and mechanical capabilities. This chapter examines the essential characteristics that render nanomaterials vital for electronic applications. Electronic characteristics, such as bandgap modification, elevated electrical conductivity, and enhanced charge carrier mobility, facilitate the creation of fast-speed and energy-efficient devices. Optical properties, including quantum confinement impacts and surface plasmon resonance, will enhance developments in displays, photodetectors, and light-emitting diodes. The thermal characteristics of nanomaterials, such as their elevated thermal conductivity and tailored phonon transport, are essential for temperature regulation in miniaturized electronics. Moreover, their remarkable mechanical strength and flexibility facilitate the advancement of next-generation flexible and mobile electronics. Case studies on graphene-based devices, carbon nanotubes, transition-metal dichalcogenides, and quantum dots demonstrate their revolutionary influence on the electronics sector. Notwithstanding the considerable promise, obstacles, including scalability, repeatability, and integration with current fabrication processes, remain. Emerging technologies like 2D heterostructures, hybrid nanomaterials, and bio-inspired electronics present interesting methods to address these limits. As research advances synthesis and integration methods, nanomaterials persist as pivotal elements in forthcoming electronic innovations.
