Photoluminescence dynamics in few-layer InSe (2020)
Journal Article
Venanzi, T., Arora, H., Winnerl, S., Pashkin, A., Chava, P., Patane, A., …Schneider, H. (in press). Photoluminescence dynamics in few-layer InSe. Physical Review Materials,

We study the optical properties of thin flakes of InSe encapsulated in hBN. More specifically, we investigate the photoluminescence (PL) emission and its dependence on sample thickness and temperature. Through the analysis of the PL lineshape, we dis...

Room temperature up-conversion electroluminescence from a mid-infrared In(AsN) tunnelling diode (2020)
Journal Article
Di Paola, D. M., Lu, Q., Repiso, E., Kesaria, M., Makarovsky, O., Krier, A., & Patanè, A. (in press). Room temperature up-conversion electroluminescence from a mid-infrared In(AsN) tunnelling diode. Applied Physics Letters,

Light emitting diodes (LEDs) for the mid-infrared (MIR) spectral range require material systems with tailored optical absorption and emission at wavelengths  > 2 μm. Here, we report on MIR LEDs based on In(AsN)/(InAl)As resonant tunnelling diodes (R...
