Terahertz (THz) band communications are envisioned as a key technology for 6G and
Beyond. As a fundamental wireless infrastructure, THz communication can boost abundant …

Terahertz (THz) radiation has attracted considerable attention in medical imaging owing to
its nonionizing and spectral fingerprinting characteristics. To date, most studies have …

An experimental study on the effects of junction capacitance and current density on the
oscillation characteristics of GaN single-drift-region (SDR) impact ionization avalanche …

Terahertz radiation has drawn enormous attention in recent times due to its various
application possibilities. This chapter reviews various emerging trends and well-established …

We report the first experimental demonstration of microwave oscillation in GaN impact
ionization avalanche time transit (IMPATT) diodes at the X-band. The device used in this …

The p+–n–n−–n+ structure, known as Hi–Lo structure, was investigated in gallium nitride
(GaN) single-drift-region (SDR) impact ionization avalanche transit-time (IMPATT) diodes to …

In this article, we propose variable-period diffraction gratings for terahertz frequencies. The
design, fabrication and characterization of such devices are presented. Our measurements …

Spectroscopic measurements in the millimeter, submillimeter, or THz range, with resolutions
exceeding a MHz, provide for highly specific detections of gas-phase absorption and …

The junction of impact ionization and avalanche transit time (IMPATT) diodes generally
operates at a higher temperature than ambient temperature. Therefore, the junction …

Spectroscopy in the terahertz (THz) band has been discussed as a promising tool for
identifying substances such as mold in food, narcotics, or explosive materials. Other than the …
