Modular and Cost-effective Scanning Photocurrent Microscopy System for Sub-micron characterization of 2D optoelectronic devices
Nuria Jiménez-Arévalo, Dan Zheng, Yong Xie +8
Scanning photocurrent microscopy (SPCM) is a powerful technique for probing local optoelectronic phenomena in 2D semiconducting devices. However, commercial setups remain costly, c…
Strongly anisotropic strain-tunability of excitons in exfoliated ZrSe
Hao Li, Gabriel Sanchez-Santolino, Sergio Puebla +5
We study the effect of uniaxial strain on the band structure of ZrSe, a semiconducting material with a marked in-plane structural anisotropy. By using a modified 3-point bendin…
An automated system for strain engineering and straintronics of 2D materials
Onur Çakıroğlu, Joshua O. Island, Yong Xie +2
This work presents an automated three-point bending apparatus that can be used to study strain engineering and straintronics in two-dimensional materials. We benchmark the system b…
Broadband-tunable spectral response of perovskite-on-paper photodetectors using halide mixing
Alvaro J. Magdaleno, Riccardo Frisenda, Ferry Prins +1
Paper offers a low-cost and widely available substrate for electronics. It posses alternative characteristics to silicon, as it shows low density and high-flexibility, together wit…
In-plane anisotropic optical and mechanical properties of two-dimensional MoO
Sergio Puebla, Roberto D'Agosta, Gabriel Sanchez-Santolino +3
Molybdenum trioxide (MoO) in-plane anisotropy has increasingly attracted the attention of the scientific community in the last few years. Many of the observed in-plane anisotro…
Optical microscopy-based thickness estimation in thin GaSe flakes
Wenliang Zhang, Qinghua Zhao, Sergio Puebla +3
We have implemented three different optical methods to quantitatively assess the thickness of thin GaSe flakes transferred on both transparent substrates, like Gel-Film, or SiO2/Si…
