Single crystal diamond schottky diodes - Practical design considerations for enhanced device performance

Novel alternatives to the conventional single crystal diamond Schottky metal-intrinsic-p+ (m-i-p+) diode is presented in this work. The conduction mechanism of the device is analysed and structural modifications to enhance its performance are proposed. The periodic inclusion of highly p+ doped thin δ-layers and p+ spots in the intrinsic voltage blocking layer of the diode drastically improves the forward performance of these devices enhancing the forward current of the device by a factor of 10 - 17 with a maximum forward current density of ̃ 40 A/cm 2 for a 2 kV device.

Enhanced performance of an all-optical parity checker using a single Mach-Zehnder interferometer

An all-optical parity checker is proposed that requires only a single Mach-Zehnder interferometer. Simulation results demonstrate an 8dB improvement in extinction ratio at 10 Gb/s operation. © 1999 Optical Society of America.
