In the α-Ag2Te phase, silver cations can move freely, which enhance the conductivity, leading to superionic conductivity [15]. More recently, it has been reported that Ag2Te is a new topological insulator with an anisotropic single Dirac cone due to a distorted antifluorite structure [14], leading to new applications in nanoelectronics and spintronics. It is also known that a huge large positive magneto-resistance SAHA HDAC clinical trial (MR) has been observed in the case of silver telluride bulk samples [18] or thin films [19]. However, to the best of our knowledge, the MR

behavior of Ag2Te nanostructured materials is rarely reported. Here, we systematically investigate the current–voltage (I-V) characteristics under different magnetic

fields and the extraordinary MR behavior of Ag2Te nanowires. The magneto-resistance can be strongly affected by the details of the Fermi surface geometry and character of electron–electron (e-e) interactions [20] and therefore gives valuable insight into the physics dominating the conductivity. Furthermore, Ag2Te with nontrivial MR can provide great opportunities in magnetic sensor and memory applications. It was reported that Ag2Te tended to form 1D nanostructures. For instance, the rod-like structure of Ag2Te was synthesized by the method based on the template-engaged synthesis in which the Te nanorods were used as DNA Damage inhibitor template reagents [21]. Ag2Te nanotubes have been synthesized hydrothermally when sodium tellurite (Na2TeO3) and silver nitrate (AgNO3) Buspirone HCl in hydrazine/ammonia mixture were autoclaved at 393 K [22]. Ag2Te NWs were obtained by cathodic electrolysis

find more in dimethyl sulfoxide solutions containing AgNO3 and TeCl4 using porous anodic alumina membrane as the template [17]. Recently, Ag2Te NWs were synthesized by a composite hydroxide-mediated method, where AgNO3 and Te powder were heated at 498 K in a Teflon vessel containing ethylenediamine and hydrazine hydrate [23]. Samal and Pradeep [24] have developed a room-temperature solution-phase route for the preparation of 1D Ag2Te NWs. In addition, our research group has more recently reported the synthesis and electrical properties of individual Ag2Te NWs via a hydrothermal process [25]. Herein, on this basis, we demonstrate a simple hydrothermal method for the synthesis of Ag2Te 1D nanostructures by employing ammonia acting as a complexing reagent and pH regulator hydrazine hydrate (N2H4 · H2O) acting as a reducing reagent. Very interestingly, we discovered the morphological evolution during the formation of 1D NWs. The morphological evolution for the 1D nanostructures is considered as the desired agent for understanding the growth mechanism and formation kinetics of crystals [26–28]. Therefore, we believe that this discoveryof the formation of 1D Ag2Te nanostructures could promote further studies and potential applications.
