HBN-encapsulated, graphene-based room-temperature terahertz receivers with high speed and low noise
Leonardo Viti, David G. Purdie, Antonio Lombardo +2
Uncooled Terahertz (THz) photodetectors (PDs) showing fast (ps) response and high sensitivity (noise equivalent power (NEP) < ) over a broad (0.5THz-10THz) frequency r…
High-mobility, wet-transferred graphene grown by chemical vapor deposition
D. De Fazio, D. G. Purdie, A. K. Ott +11
We report high room-temperature mobility in single layer graphene grown by Chemical Vapor Deposition (CVD) after wet transfer on SiO and hexagonal boron nitride (hBN) encapsula…
A peeling approach for integrated manufacturing of large mono-layer h-BN crystals
Ruizhi Wang, David G. Purdie, Ye Fang +8
Hexagonal boron nitride (h-BN) is the only known material aside from graphite with a structure composed of simple, stable, non-corrugated atomically thin layers. While historically…
Cleaning Interfaces in Layered Materials Heterostructures
D. G. Purdie, N. M. Pugno, T. Taniguchi +3
Heterostructures formed by stacking layered materials require atomically clean interfaces. However, contaminants are usually trapped between the layers, aggregating into blisters.…
Broadband, electrically tuneable, third harmonic generation in graphene
G. Soavi, G. Wang, H. Rostami +16
Optical harmonic generation occurs when high intensity light (W/m) interacts with a nonlinear material. Electrical control of the nonlinear optical response enables…
Out-of-plane heat transfer in van der Waals stacks: electron-hyperbolic phonon coupling
K. J. Tielrooij, N. C. H. Hesp, A. Principi +20
Van der Waals heterostructures have emerged as promising building blocks that offer access to new physics, novel device functionalities, and superior electrical and optoelectronic…
Few-cycle pulses from a graphene mode-locked all-fiber laser
D. Purdie, D. Popa, V. J. Wittwer +6
We combine a graphene mode-locked oscillator with an external compressor and achieve~29fs pulses with~52mW average power. This is a simple, low-cost, and robust setup, entirely fib…
