A flat-band perspective on the boson peak in amorphous solids

The boson peak is a characteristic anomaly of amorphous solids broadly defined as a low-energy excess in the density of states and heat capacity compared to the textbook predictions of Debye theory. The origin of this anomaly has long been the subject of ongoing debate and remain...

High‐Responsivity and Fast‐Response Organic Phototransistor Based on Dinaphtho[2,3‐b:2′,3′‐f]Thieno[3,2‐b]Thiophene

ABSTRACT Organic phototransistors (OPTs) are promising as low‐cost detectors compatible with plastic‐substrate electronics for visible light communication (VLC) systems. However, enhancing their sensitivity without sacrificing speed remains challenging. In this work, we report on...
