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…
Integrating van der Waals materials on paper substrates for electrical and optical applications
Wenliang Zhang, Qinghua Zhao, Carmen Munuera +12
Paper holds the promise to replace silicon substrates in applications like internet of things or disposable electronics that require ultra-low-cost electronic components and an env…
Thickness identification of thin InSe by optical microscopy methods
Qinghua Zhao, Sergio Puebla, Wenliang Zhang +3
Indium selenide (InSe), as a novel van der Waals layered semiconductor, has attracted a large research interest thanks to its excellent optical and electrical properties in the ult…
Giant piezoresistive effect and strong band gap tunability in ultrathin InSe upon biaxial strain
Qinghua Zhao, Tao Wang, Riccardo Frisenda +1
The ultrathin nature and dangling bonds free surface of two-dimensional (2D) semiconductors allow for significant modifications of their band gap through strain engineering. Here,…
InSe Schottky diodes based on van der Waals contacts
Qinghua Zhao, Wanqi Jie, Tao Wang +2
Two-dimensional semiconductors are excellent candidates for next-generation electronics and optoelec-tronics thanks to their electrical properties and strong light-matter interacti…
The role of traps in the photocurrent generation mechanism in thin In-Se photodetectors
Qinghua Zhao, Wei Wang, Felix Carrascoso-Plana +4
Due to the excellent electrical transport properties and optoelectronic performance, thin indium selenide (InSe) has recently attracted attention in the field of 2D semiconducting…
