Although van der Waals layered transition metal dichalcogenides from transient absorption spectroscopy have successfully demonstrated an ideal carrier multiplication (CM) performance with onset of nearly 2Eg,interpretation the CM effect optical approach remains unresolved owing to complexity many-body electron-hole pairs. We demonstrate through simple photocurrent measurements by fabricating du...

The powerful concept of an operator ideal on the class of all Banach spaces makes sense in the real and in the complex case. In both settings we may, for example, consider compact, nuclear, or 2–summing operators, where the definitions are adapted to each other in a natural way. This paper deals with the question whether or not that fact is based on a general philosophy. Does there exists a one...
