High-frequency, 6.2 Å pN heterojunction diodes
نویسندگان
چکیده
Sb-based pN heterojunction diodes at 6.2 Å, consisting of narrow bandgap p-type In0.27Ga0.73Sb and wide bandgap n-type In0.69Al0.41As0.41Sb0.59, have been fabricated and measured. These diodes show excellent electrical characteristics with an ideality factor of 1.2 and high current density. S-parameter measurements and subsequent analysis show that these diodes have RC-cutoff frequencies over 1 THz, making these diodes excellent choices for high-frequency applications, such as sub-harmonic mixers for frequency conversion.

Antimonide-based pN terahertz mixer diodes
High frequency pN heterojunction diodes with cutoff frequencies over 1 THz have been fabricated using narrow bandgap high-mobility semiconductors. The pN heterojunction is composed of a 30 nm thick p-type In0.27Ga0.73Sb alloy and a 130 nm thick In0.69Al0.31As0.41Sb0.59 n-layer. A high-mobility n-type InAs0.66Sb0.34 contact layer is used to connect the mesa diode to a metal Ohmic contact. These ...
متن کاملAn Heterojunction Schottky Barrier Diode with RTD Emitter
The possible application of Schottky diodes as detector elements in receivers and image sensing systems operating in the THz frequency range has been demonstrated in the literature. In addition to metal-semiconductor (M-S) Schottky diodes, the use of heterojunction Schottky barrier diodes for detection and mixing applications has also been explored. Such diodes require lower d.c. bias voltages,...
متن کاملAlGaAs Anode Heterojunction PIN Diodes
This paper describes the development of a heterojunction AlGaAs/GaAs PIN diode as a revolutionary improvement as compared to the homojunction GaAs PIN diode commonly used in microwave systems for commercial and military applications. In a heterojunction device the injected carriers from the junction are confined by the bandgap discontinuity between the AlGaAs/GaAs layers. This confinement effec...

متن کاملUltrahigh-Speed Multiple-Threshold Comparator Using Resonant-Tunneling Diodes and Heterojunction FETs
An ultrahigh-speed multiple-threshold comparator that consists of resonant-tunneling diodes (RTDs) and heterojunction FETs has been investigated. A novel multiple-threshold operation is obtained by detecting a switching sequence in a series-connected RTD circuit. SPICE simulation reveals that the present comparator operates at a clock frequency as high as 10 GHz. One FET at the input is enough ...
