They can exist in both a semiconducting 1H-phase and a quasi-metallic 1T\u2019-phase, with each having a different crystal structure. The 1T\u2019-phase is particularly interesting as theoretical predictions show that it has potential to be used in less conventional applications, such as super capacitor electrodes and hydrogen evolution reaction catalysts. However, the quantity of 1T\u2019-phase 2D-TMDs that can be obtained by converting them from the 1H-phase through a phase transition process is low. This potentially limits the use of such novel materials for a wide range of applications.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif\">A research team led by Prof Andrew WEE from the Department of Physics, NUS has discovered that, while different 2D-TMD materials have their own intrinsic energy barriers when transiting from the 1H to the 1T\u2019 structural phase, the use of a metallic substrate with higher chemical reactivity can significantly increase the 1H- to 1T\u2019- phase transition yield. This is a convenient and high-yielding method to obtain 2D-TMD materials in their 1T\u2019 metallic phase. When the 2D-TMD material is placed in contact with the metal substrate (e.g. gold, silver and copper), electric charges are transferred from the metal substrate to the 2D-TMD material. Furthermore, it weakens the bond strength of the 2D-TMD structure significantly and increases the magnitude of the interfacial binding energy. This in turn increases the susceptibility of the 1H-1T&#8217; structural phase transition. As a result, this enhanced interfacial hybridisation at the interface of the two materials makes the 1H-1T\u2019 structural phase transition much easier to achieve.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif\">The research team combined multiple experimental techniques and first-principles calculations in their research work. These includes optical spectroscopies, high resolution transmission electron microscopy and density functional theory based first-principles calculations to identify the phase changes (1H- and 1T&#8217;-phases) of the 2D-TMDs in the samples.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif\">This study provides new insights on the influence of interfacial hybridisation affecting the phase transition dynamics of 2D-TMDs. The findings can potentially be used in a model system for the controlled growth of 2D-TMDs on metallic substrates, creating possibilities for new 2D-TMDs-based device applications.<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif\">Prof Wee said, \u201cThe controllability of the semiconductor to metal phase transition at the 2D-TMD and metal interfaces can enable new device applications such as low contact resistance electrodes.\u201d<\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif\"><img decoding=\"async\" alt=\"\" src=\"https:\/\/www.science.nus.edu.sg\/wp-content\/uploads\/2019\/11\/188._Wee_A_20190114_2.jpg\" \/><\/span><\/p>\n<p><span style=\"font-family: arial, helvetica, sans-serif\">Figure 1: (Top) The structural evolution of 1T\u2019-phase monolayer molybdenum disulphide (MoS<sub>2<\/sub>) and tungsten diselenide (WSe<sub>2<\/sub>) from the 1H-phase.
