Wireless communication systems, from IoT devices to future 6G networks, are becoming increasingly complex and energy‑hungry.
A significant share of this energy is consumed in the radio‑frequency (RF) front‑end, where signals are generated, tuned, and transmitted. Improving the efficiency and adaptability of these front‑ends is therefore essential for sustainable wireless technologies.
My research focuses on developing ferroelectric RF components based on hafnium zirconium oxide (HZO) for tunable and energy‑efficient wireless front‑ends at millimeter‑wave and sub‑terahertz frequencies. Ferroelectric HZO enables low‑power, electrically tunable, and CMOS‑compatible devices, offering a low‑loss alternative to conventional RF tuning technologies.
I will design and characterize ferroelectric HZO based RF devices using cleanroom fabrication and high frequency measurements, applying S parameter analysis and de-embedding to evaluate tunability, quality factor, and parasitic effects.
