Laser doping of 2D material for precise energy band design

Abstract

Excellent 2D materials are finite for nano optoeletric devices including transistors, diodes, sensors, and so forth, thus modulation of 2D materials is important to improve performace of the current eligible...

Research on Surface-Enhanced Raman Spectroscopy and Simulated Laccase Activity of Two-Dimensional Metal Sulfide Nanosheets

“…Since the initial discovery of graphene, interest in two-dimensional (2D) layered materials has significantly intensified. These materials display distinct electrical, thermal, magnetic, and optical characteristics, rendering them attractive for diverse applications, such as nanophotonics, nanodevices, sensing, and catalysis. − The physical and chemical attributes of 2D materials can be engineered through doping, , introduction of defects, , incorporation into composites, and exposure to external electric fields, thereby greatly enhancing their practical application potential. Surface-enhanced Raman scattering (SERS) is a highly sensitive molecular spectroscopic technique that provides structural insights into substances.…”

Broad -band nonlinear optical response in Bi2Te0.6S2.4 alloys based on alloy engineering

“…In contrast, the doping and alloying of semiconductors 26–29 to broaden the response range of light has attracted widespread attention by virtue of controllability and effectiveness. As a result, a large number of works have reported that the bandgap of Bi 2 S 3 can be modulated by doping engineering.…”

Direct Laser Writing: From Materials Synthesis and Conversion to Electronic Device Processing

“…Lasers and their high‐throughput material processing capabilities have amassed a great focus of research over the years, as a comprehensive resource to complement and substitute many manufacturing paradigms for more versatile approaches. The integrated capability of laser systems to participate in several fabrication stages, from synthesis, [ 18 ] doping, [ 19 ] polymerization, [ 20 ] and curing, [ 21 ] simultaneously with patterning, [ 22 ] and assembly, [ 23 ] has made laser technologies an important asset in material engineering and processing.…”

“…Examples of transformative approaches include the crystallization of amorphous materials, [ 29 ] laser‐promoted reversible structural transformations of carbon‐based materials, [ 30 ] or laser doping of semiconductors. [ 19 ]…”
