The realization of electronic devices based on heterostructures metallic, semiconducting, or insulating two-dimensional materials relies the ability to form structurally coherent and clean interfaces between them, vertically laterally. Lateral that fuse together two different in a well-controlled manner have attracted recent attention, but methods seamless dissimilar materials, such as graphene...

یکی از جذاب ترین روش های ماشینکاری مدرن، تخلیه الکتریکی است که در اواخر دهه 1960 معرفی شد. با سیم کاربردهای مختلفی دارد، جمله دقت بالا تمام مواد رسانا مانند فلزات، آلیاژهای فلزی، گرافیت و سرامیک همچنین صنایع هوافضا، خودروسازی سایر صنایع. به منظور افزایش سرعت کاهش زبری سطح عرض شکاف، پارامترهای برش بهینه نقش مهمی انتخاب خروجی دارند. این مطالعه، ورودی (دبی، مدت پالس، فرکانس سیم، کشش جریان دی الکتر...

Developing a nanoscale, integrable, and electrically pumped single mode light source is an essential step toward on-chip optical information technologies and sensors. Here, we demonstrate nanocavity enhanced electroluminescence in van der Waals heterostructures (vdWhs) at room temperature. The vertically assembled light-emitting device uses graphene/boron nitride as top and bottom tunneling con...

The remarkable properties of graphene and transition metal dichalcogenides (TMDCs) have attracted increasing attention on two-dimensional materials, but the gate oxide, one of the key components of two-dimensional electronic devices, has rarely reported. We found the single-layer oxide can be used as the two dimensional gate oxide in 2D electronic structure, such as TiO2. However, the electrica...

The isolation of various two-dimensional (2D) materials, and the possibility to combine them in vertical stacks, has created a new paradigm in materials science: heterostructures based on 2D crystals. Such a concept has already proven fruitful for a number of electronic applications in the area of ultrathin and flexible devices. Here, we expand the range of such structures to photoactive ones b...
