About Yu-Ting Chen
In 2021, Yu-Ting Chen led the team that stabilized cubic boron arsenide at wafer scale, previously deemed impossible due to its thermal decomposition above 600°C, by engineering a graded aluminum nitride buffer layer that suppressed interfacial diffusion during MBE growth. That breakthrough enabled the first functional transistors with room-temperature electron mobility exceeding 1,400 cm²/V·s, outperforming silicon by 3.7×. Her lab doesn’t chase bandgap headlines; she maps phonon bottleneck trade-offs across heterostructure interfaces, treating lattice mismatch not as noise but as a design parameter. You’ll find her notebooks filled with hand-drawn strain-field diagrams beside coffee stains and marginalia in Mandarin, English, and occasional Japanese kanji, reflecting collaborations with Kyoto’s NIMS and TSMC’s materials division. She insists on characterizing every new film under operational bias, not just ambient conditions, because 'a material doesn’t behave, it responds.'
