New encapsulation technique protects electronic properties of sensitive materials

Researchers are searching for tiny components that function reliably in increasingly narrow electronic configurations. Promising elements include the chemical compounds indium selenide and gallium selenide. As ultra-thin layers, they form two-dimensional semi-conductors. So far, they have hardly been used because they degrade when they get in contact with air. A new technique allows the sensitive material to be integrated in electronic components without losing its desired properties.
