0.53 mΩ.cm 2 /592 V High Breakdown Voltage GaN-on-Sapphire Schottky Diodes Without Edge Termination

Hugo Bouillaud, Beatriz Orfao, Etienne Okada, Yannick Roelens, Malek Zegaoui, Mohammed Zaknoune

In this letter, we report high-performance Pt/GaN quasi-vertical Schottky barrier diodes on sapphire substrate. With a 5 μm drift layer and a highly controlled fabrication process, the devices demonstrate an extremely low on-resistance of 0.53 mΩ.cm² while exhibiting a high breakdown voltage of 592…

Far-Field Terahertz Spectroscopy of a Subwavelength Single Planar Meta-Atom

Surya Revanth Ayyagari, Simonas Indrišiūnas, Guillaume Ducournau, Vytautas Janonis, Irmantas Kašalynas

Accurate measurements of light-matter interactions at subwavelength scales are critical for advancing nanophotonic and quantum optical technologies. In this paper, we present the far-field terahertz (THz) spectroscopy of a single planar meta-atom of subwavelength dimensions embedded within a square…

Chapter 9 - One open loop, two stubs, and two infinite leads

Housni Al-Wahsh, Eman Abdel-Ghaffar, Abdellatif Akjouj, Madiha Amrani, Leonard Dobrzyński

The present system is constructed out of one open loop of length L, two stubs of length , and two infinite leads. It is shown that the transmission properties of such a system depend on its bulk states localized in the whole structure and on infinite bound in continuum (IBIC) states. These IBICs…

Transfer of mTRL Accuracy in industrial BiCMOS Technology to commercial Lumped-Element Calibrations up to 110 GHz

Gia Ngoc Phung, Uwe Arz, Samuel Nguyen Dinh An, Joao Azevedo Goncalves

Currently, on-wafer traceability is directly linked to multiline TRL (Thru Reflect Line), which is widely recognised as one of the most accurate on-wafer calibration methods. However, fixed-distance calibrations, such as Short Open Load Thru (SOLT) and Line Reflect Match (LRM), which use commercial…
