Abstract :
Schottky diode structures with Ge quantum dots (QDs) have been grown by Molecular Beam Epitaxy (MBE). They have been employed to fabricate NiSi Schottky diodes with Ge dots buried below the metal-semiconductor junctions. These diodes have cut-off frequencies up to 1.1 THz (calculated from S-parameter measurements up to 110GHz). Preliminary results demonstrating the implementation of Ge QD Schottky diode in a mm-wave power detection system (RECTENNA) are also presented.
