New synthesis method of 'graphene' with 100 times electron mobility of silicon announced

ByPNNL - Pacific Northwest National Laboratory

GrapheneIs 100 times as large as siliconElectron mobilityIt has high thermal conductivity, is more durable than steel, is flexible and also suitable for electronic equipment. It is the first time in the world that such graphene is synthesized as practical scale single crystal grapheneSamsung Advanced Technology Research Institute (SAIT)WhenSungkyunkwan UniversityIt is announced by joint development of.

Graphene is 100 times as large as siliconElectron mobilityIt combines durability and flexibility, it is a material suitable for electronic equipment such as flexible display and wearable device because of its characteristics. Although no device using graphene has appeared so far because there is no practical processing method, we found a method to synthesize large graphene which SAIT and the group of Sungkyunkwan University could not do before. Current siliconWaferIt becomes possible to synthesize semiconductor wafer-scale single crystal graphene which is used in Sapporo, and it has become possible to become a breakthrough in graphene commercialization by becoming able to hold electric charge of larger scale than before.

On Neowin's successful synthesis of monocrystalline graphene, There have been no outcomes other than lithium ions over the past few decades "Battery innovation"I express it. If research progresses and commercialization succeeds, it becomes common for small wearable devices to be equipped with a long life battery that breaks the upper limit of the conventional lithium ion battery in terms of volume and weight, and smart phones and tablets It is possible that it is suitable for the development of flexible displays due to its miniaturization and its flexibility.


The results of the research are"Science" issued on April 4It is published in.
