High-frequency metal-insulator-metal (MIM) diodes for thermal radiation harvesting. (2015)
Presentation / Conference Contribution

The fabrication of low-cost metal-insulator-metal (MIM) diodes using a self-assembled monolayer as the insulating layer is presented. DC and AC analysis show that the diodes have excellent non-linear current voltage characteristics compared to those...

Free-space material characterisation at terahertz frequencies using a vector network analyser (2015)
Presentation / Conference Contribution

While dielectric properties of many materials have been extensively characterised at low frequencies and into the microwave region of the electromagnetic spectrum, published information is much sparser in the THz region. Knowledge of permittivity is... Read More about Free-space material characterisation at terahertz frequencies using a vector network analyser.

Effect of Wood’s Anomalies on the THz Transmission Spectra of Free- Standing Metallic Hole Arrays (2015)
Presentation / Conference Contribution

A free-standing periodic array of subwavelength rectangular apertures has been designed to exhibit peak transmission which is dominated by localized aperture resonance in the THz region. By varying the incident angle, Wood's anomalies can be introduc... Read More about Effect of Wood’s Anomalies on the THz Transmission Spectra of Free- Standing Metallic Hole Arrays.

Wireless power transfer (WPT) technologies have been widely used in many areas, e.g., the charging of electric toothbrush, mobile phones, and electric vehicles. This paper introduces fundamental principles of three WPT technologies, i.e., inductive c... Read More about Wireless Power Transfer: Survey and Roadmap.

THz Imaging with Broadband Thermal Sources (2014)
Presentation / Conference Contribution

We developed a THz imaging system based on a broadband thermal source (at 500°C) and an asymmetric semiconductor nanochannel, the self-switching nanodiode (SSD), as a room-temperature detector. The maximum resolution was better than 0.5 mm full width... Read More about THz Imaging with Broadband Thermal Sources.

Rectennas for Thermal-Energy Conversion (2014)
Presentation / Conference Contribution

We demonstrated the conversion of thermal energy in the form of far- and mid-infrared using a micro rectenna, consisting of a spiral antenna coupled to an ultra-fast nanodiode, the so-called self-switching device (SSD). A maximum efficiency of 0.02 %... Read More about Rectennas for Thermal-Energy Conversion.
