Fabrication and Study of Broadband MIM Detector-Mixer

摘要

Chemical, mechanical (geometrical), electrical and thermal stability parameters of the metal-oxide (insulator)-metal (MOM of MIM) diodes based on point contact and discontinuous metal film structures have been examined exhaustively for diode stabilization and optimization of performance for mm wave and near infrared laser detection and mixing. Preliminary observations and analysis have indicated possibility of achieving long term stability with little loss of the ultrahigh frequency of operation and ultrabroad bandwidth of these devices. As instability is greatly reduced, fundamental physics of the conduction mechanisms and their regimes of operation should then be unambiguously analyzed and identified. The techniques acquired have led to the initial fabrication of thin film chip diode arrays for efficient detection and mixing.
