Through careful selection of suitable dopants and ionic liquids, High doping levels are achieved remarkably in a short period, resulting in the highest conductivity (nearly 1 × 10 − 2 S cm − ¹) compared to other doping
“Doping” of semiconductors—that is, the local manipulation of their conductivity—is a key technology for electronic devices. Without doping, for example, a gallium nitride sample larger than the White House would be

Adding even a single impurity atom to a semiconductor NC with a diameter of 4 nm, which contains about 1000 atoms, leads to a nominal doping level of 7 × 10 19 cm –3.In a bulk semiconductor this is already well within the
Jul 7, 2005Doping—the intentional introduction of impurities into a material—is fundamental to controlling the properties of bulk semiconductors. This has stimulated similar efforts to dope semiconductor
- What are the most successful products based on doping?
- The most successful product so far is the organic light-emitting diode display with a multibillion U.S. dollar market, which are using doping by controlled coevaporation of small-molecule semiconductors and dopant molecules ( 5 ). The microscopy nature of doping in organic semiconductors is strongly different from inorganic semiconductors ( 6 ).
- What is semiconductor doping?
- Semiconductor doping is a key process in electronics. It involves adding tiny amounts of specific impurities to a pure semiconductor material, like silicon, to change its electrical properties. This process helps the semiconductor conduct electricity better and makes electronic devices like transistors and diodes work properly.
- What is doping of bulk semiconductors?
- Doping of bulk semiconductors, the process of intentional insertion of impurity atoms into a crystal, was introduced in the 1940s and is the basis for the widespread application of semiconductors in electronic and electro-optic components (1).
- What is modulation doping?
- Modulation doping is a widely used doping method in inorganic semiconductors where a heavily doped wide bandgap semiconductor is brought in contact with a narrow bandgap semiconductor. Efficient doping at the heterostructure interface is achieved by charge transfer from the wide bandgap semiconductor to the narrow bandgap semiconductor.
- What is the microscopy nature of doping in organic semiconductors?
- The microscopy nature of doping in organic semiconductors is strongly different from inorganic semiconductors ( 6 ). One particularly relevant difference is that the dopant concentrations in organic are usually orders of magnitude higher than in inorganics to saturate the high level of deep traps in these materials ( 7 ).
- Can two-dimensional semiconductor substitutional doping be used for thin films?
- In this study, we devise a precise method for two-dimensional (2D) semiconductor substitutional doping, which allows for the production of wafer-scale 2H-MoTe 2 thin films with specific p -type or n -type doping.
