In the era of the Internet of Things (IoTs), sensors, portable electronics, wearable devices, and wireless transport systems are increasing the demand for renewable and green energy supplies. Triboelectric nanogenerators (TENGs) have been actively investigated and extensively developed, aiming for efficiently converting environmental [ Learn more ]

The dual-comb is a novel technique that can be used in many practical applications in spectroscopy, imaging, communications, and so on. In the spectroscopic field, the traditional techniques, e.g., Fourier transform infrared spectroscopy, time-domain spectroscopy, etc., require a moving part to obtain the spectra of samples, which makes it hard to perform the real-time spectral measurement.

Towards the fundamental research and device applications of two-dimensional (2D) materials, hexagonal boron nitride (h-BN) is the ideal dielectric substrate and encapsulating layer due [ Learn more ]

Since the first demonstration of optical frequency combs in the infrared frequency regime, the study of frequency combs in various wavelengths attracts more and more interests. Because of high frequency stability and short pulse generation (if mode-locking can be applicable), the frequency comb can significantly improve the spectral and time accuracies[ Learn more ]

Two dimensional (2D) hexagonal boron nitride (h-BN) is an extraordinary mesh consisting of alternating sp2-bonded boron and nitrogen atoms. [ Learn more ]
