Gas sensors are frequently used for detecting toxic gases and vapors environmental control, industrial monitoring household safety. Semiconductor conductivity can be modified by doping or fine-tuned applying an electric magnetic field in ultra-wide range (10 −7 S cm −1 to 10 2 ). The conduction of semiconductor is significantly raised reduced upon the exposure external conditions, such as tempe...

Generating large topologically protected surface currents using conventional III–V infrared materials such as InAsSb/InGaSbAs quantum wells (QWs) and superlattices (SLs) has been important. In materials, topological states can be formed at the edge by hybridizing ordinary electronic band structures. However, achieving out of these is still difficult due to low emission high carrier defects. thi...

In the past several decades, semiconductor materials have been used in a wide range of electronic devices. These devices include transistors, light emitting diodes, lasers, photodetectors, solar cells, and many more. Given such an impressive range of applications, one might wonder what makes semiconductors so different from other materials? At the heart of it, semiconductors are different from ...
