项目摘要

Solid state devices are the backbone of all the modern electronics like cell phones, computers, televisions, and many other electronics which are used in daily life. Materials like silicon which are inorganic have been used as the semiconductor material for devices which are used in these electronics. There is a quest for other materials which can extend the speed and the device properties. Silicon has covalent bonding whereas a set of new materials referred to as two dimensional (2D) materials have covalent bond within a monolayer but are bond to the other layers via Van der Waals forces. Obtaining monolayers which are less than a nanometer thick is relatively easy with these 2D materials due to the bonding of the atoms. These 2D materials have different properties offering an array of metal, semiconductors, and insulators. Hence, these materials can be stacked like Lego with different materials to obtain novel properties. Thus, these materials can be utilised for developing new electronic and optical devices. These devices can be used for a wide variety of applications ranging from flexible electronics which could include light emission, detection, transistors, etc. to name a few. One of the main challenges with the 2D materials has been large scale growth of high-quality material for reproducible devices. The project will used pulsed laser deposition for large are growth of high quality 2D materials and develop electronic devices.

固态设备是所有现代电子产品的支柱，如手机，电脑，电视和日常生活中使用的许多其他电子产品。像硅这样的无机材料已经被用作这些电子设备中使用的器件的半导体材料。存在对可以扩展速度和设备特性的其他材料的探索。硅具有共价键合，而一组称为二维（2D）材料的新材料在单层内具有共价键，但通过货车德瓦尔斯力键合到其它层。由于原子的键合，使用这些2D材料获得小于纳米厚度的单层相对容易。这些2D材料具有不同的属性，提供了金属，半导体和绝缘体的阵列。因此，这些材料可以像乐高一样堆叠不同的材料，以获得新的特性。因此，这些材料可用于开发新的电子和光学器件。这些器件可以用于各种各样的应用，范围从可以包括光发射、检测、晶体管等的柔性电子器件到仅举几例。2D材料的主要挑战之一是大规模生长用于可再生器件的高质量材料。该项目将使用脉冲激光沉积技术来大面积生长高质量的2D材料，并开发电子设备。
