Hafnium telluride (HfTe₂) is a layered transition metal dichalcogenide material with unique electronic properties, including charge density waves and potential superconductivity. It is explored in nanoelectronics for 2D transistors and field-effect devices due to its semiconducting behavior and tunable bandgap. Applications include optoelectronic devices such as infrared detectors and sensors, leveraging its response to light. Its high thermal stability makes it suitable for harsh environments, including protective coatings and aerospace components. Ongoing research focuses on its topological insulator properties for quantum materials and next-generation electronic systems.
