Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

open access: yesHeat Transfer, EarlyView.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

High performance RF power MOSFET

open access: yesElectronics Letters, 2002
A novel high voltage silicon RF LDMOSFET in SOI technology based on the 3D-RESURF concept is proposed. For the same blocking voltage rating, the new structure allows the LDMOSFET to have higher current handling capability at high gate voltages. This in turn causes the transconductance to be higher, leading to overall better RF performance.
