What is it about?
Two-dimensional materials, like WSe2 monolayers, are redefining what's possible in electronics and optics. Our recent study explored the interaction of WSe2 with indium tin oxide (ITO), a key material in transparent conducting electrodes used in optoelectronic devices.

Why is it important?
These findings highlight the potential of 2D materials in advanced heterostructures and give insights for better design and control of next-gen optoelectronic devices.
Perspectives
Key takeaways: ● WSe2 remains optically active even when transferred onto ITO, showcasing the absence of optical quench in this conducting substrate. ● Thermal annealing reduces atmospheric adsorbates trapped during fabrication, indicating their volatile nature. ● Photoluminescence and n-doping properties are influenced by these adsorbates, offering insights for tuning material behavior.
