| Abstract Scope |
Two-dimensional (2D) van der Waals (vdW) materials, such as transition metal dichalcogenides (TMDs), have garnered significant attention due to their unique electrical and optical properties, even when scaled to a few atomic layers. However, conventional fabrication methods like mechanical exfoliation are not compatible with semiconductor processes or mass production. Although chemical vapor deposition (CVD) and physical vapor deposition (PVD) have been explored, these techniques require high deposition temperatures due to the high melting points of TMDs. Therefore, we have focused on quasi one-dimensional (q1D) vdW materials, which typically exhibit low melting points and rich electronic properties similar to TMDs. For instance, NbTe4 thin films have been successfully fabricated using sputtering and post-annealing at moderate temperatures around 270°C. This study also proposes using the same method for fabricating a q1D ZrTe5 thin films, a well-known Weyl and Dirac semimetal, whose phase change behavior has been systematically investigated. |
