“Background During the past few decades, a shape-controlled synthesis of semiconducting crystals with well-defined morphologies, such as belts, wires, rods, tubes, spheres, sheets, combs, and cubes, has attracted considerable attention due to their novel properties and applications in many

fields [1–7]. Among these nanostructures, one-dimensional (1D) nanostructures have increasingly become the subject of intensive research due to their potential applications in a variety of novel devices [8–10]. The most prominent example is certainly the carbon nanotubes [11, 12]. Not only that, considerable efforts have been spent on Thymidylate synthase the synthesis of nanobelts, nanowires (NWs), and other 1D nanostructures. Especially, with the miniaturization of devices in the future, searching for interconnects remains a challenge to future nanoelectronics. Therefore, it is essential to investigate 1D nanomaterials which can be applied in the nanoscale field. As one typical example of the silver chalcogenides, Ag2Te has attracted increasing attention due to its much more technological prospects [10, 13, 14]. As reported, Ag2Te can transfer its structural phase from the low-temperature monoclinic structure (β-Ag2Te) to the high-temperature face-centered cubic structure (α-Ag2Te) at about 145°C [15, 16].
