This research landscape is significantly shaped by the advancement of heterostructured nanomaterials, which engineer interfaces between different materials to achieve superior charge transport capabilities. These meticulously designed structures are paramount in enhancing the performance of critical energy conversion and storage technologies, including photovoltaics, photocatalysis, and batteries. The deliberate creation of specific band alignments at these heterojunctions is a core strategy to effectively guide and separate charge carriers, minimizing recombination losses and maximizing efficiency [1].
A promising frontier in this field is the development of novel two-dimensional (2D) heterostructures. Through methods like van der Waals assembly, diverse 2D materials can be precisely stacked to form interfaces with finely tuned electronic properties. This level of control allows for tailored band offsets and consequently, more efficient charge separation, which is indispensable for the next generation of advanced electronic and optoelectronic devices [2].
Within the domain of solar energy, perovskite solar cells (PSCs) have experienced remarkable progress, with heterostructuring playing a pivotal role in their escalating efficiency. The integration of perovskite layers with specialized charge transport layers, often within sophisticated heterojunction architectures, is essential for the effective extraction of photogenerated charges. A deep understanding of the interfacial energetics and the dynamic behavior of charges at these junctions is crucial for further advancements in PSC performance and long-term stability [3].
Quantum dots (QDs) are fundamental components in numerous optoelectronic devices, and their functional performance is intrinsically linked to efficient charge transport. The fabrication of heterostructures incorporating QDs, such as QD/semiconductor or QD/metal interfaces, offers a powerful means to significantly improve charge injection and extraction processes. Judicious selection of constituent materials and meticulous interface engineering are key to unlocking enhanced photocatalytic and sensing applications [4].
Nanowire heterostructures present distinct advantages for charge transport, owing to their intrinsically high surface area and precisely controlled dimensionality. By constructing core-shell or segmented nanowire architectures, researchers can effectively integrate materials possessing complementary electronic characteristics.
