Titolo: Tuning the electronic, optical and transport properties of ultrathin van der Waals materials.
Abstract:
Since their discovery, two-dimensional (2D) materials derived from van der Waals crystals have garnered significant attention due to their exceptional properties. The reduced dimensionality and extreme aspect ratio of these materials enable unprecedented tunability of their physical characteristics, far beyond what is achievable in bulk materials. This versatility has opened new avenues for researchers to manipulate their electronic and optical properties through various means, including electric fields, mechanical strain, chemisorption of atoms or molecules, and the assembly of normal or twisted heterostructures.
In this seminar, I will present recent advancements in tuning the optical, electrical, and transport properties of 2D metals such as graphite and 1T-TaS2, as well as 2D semiconductors like MoS2 and InSe, along with devices based on these materials. By leveraging a combination of complementary experimental techniques — such as optical spectroscopy, photoemission spectroscopy, and transport measurements — I will demonstrate how the properties of 2D materials can be precisely controlled to enhance device performance.
