大表面积、催化剂颗粒高度分散不会聚集 Graphene communicating platform has the ability to store and transfer electrons to different locations on the platform due to its redox properties. having two different catalyst particles in different locations on the same sheet can provide greater versatility for ...
A new structure using finger-shaped magnetic vias has been introduced resulting in > 30% Q-factor increase. On-chip RF spiral and stripline inductors were fabricated and enhancements of 9.1X in inductance and 4X in quality factor with good frequency response were obtained. Optimizing finger-shaped...
