快速热处理化学气相沉积法制备用于电子产品热管理的轻质柔性石墨烯
Flexible and lightweight graphene grown by rapid thermal processing chemical vapor deposition for thermal management in consumer electronics
摘要
Abstract
Next-generation consumer electronics require excellent thermal management.Graphene is a good choice because its thermal conductivity is 13 times that of copper.Single-,bi-and few-layer graphene(SLG,BLG,FLG)with large sp2 domains were grown by rapid thermal processing chemical vapor deposition(RTP-CVD)from CH4 and H2 using Ar as the diluting gas.The quality of graphene was investigated by Raman spectroscopy and TEM.To demonstrate the heat dissipation capability of RTP-CVD-grown graphene,a 2 TB solid state drive was used and the temperature was measured by a FLIR thermal camera.Results indicate that high thermal conductivity graphene was prepared by diluting the precursor gas with Ar.SLG was prepared at a growth temperature of 1 000 ℃ and a time of 25 min.A transition from FLG to high-quality BLG was observed at low H2 concentrations.Using SLG,there was a 5 ℃ lower temperature rise than using a commercial copper heat dissipator.The heat dissipation ability of SLG was approxim-ately 200 times that of commercial copper heat dissipators.关键词
