ISO 22197-1 - This part of ISO 22197 specifies a test method for the determination of the air-purification performance of materials that contain a photocatalyst or have photocatalytic films on the ...
Researchers can now fabricate a 3D chip with alternating layers of semiconducting material grown directly on top of each other. The method eliminates thick silicon substrates between the layers, ...
Semiconducting transition metal dichalcogenides (TMDs) are a class of layered materials exhibiting unique optoelectronic properties that could be leveraged to develop transistors, sensors and ...
So, chip manufacturers are looking to build up rather than out. Instead of squeezing ever-smaller transistors onto a single surface, the industry is aiming to stack multiple surfaces of transistors ...
