Doping of Soft Semiconductors | ACS Energy Letters
In organic semiconductors, electronic doping is considered a way to surgically control the electronic properties of organic devices such as light-emitting diodes, photodetectors, thermoelectrics, solar cells, field-effect transistors, and lasers. It is already implemented, with small molecules, in commercially available OLED displays.
Doping (semiconductor)
In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor.

6.1.2.1.3 Dopant Effects. The doping elements like boron, phosphorus, and arsenic are inevitably present in the oxidation processes of the silicon devices as the oxide growth consumes silicon material. This fact influences the oxide growth and also the element concentration distribution. Let us first consider the doping element redistribution
7.1.4: Semiconductors- Band Gaps, Colors, Conductivity and Doping
n- and p-type doping of semiconductors involves substitution of electron donor atoms (light orange) or acceptor atoms (blue) into the lattice. These substitutions introduce extra electrons or holes, respectively, which are easily ionized by thermal energy to become free carriers.
Doping limits in p -type oxide semiconductors - Springer
The ability to dope a semiconductor depends on whether the Fermi level can be moved into its valence or conduction bands, on an energy scale referred to the vacuum level. For oxides, there are various suitable n-type oxide semiconductors, but there is a marked absence of similarly suitable p-type oxides. This problem is of interest not only for thin-film transistors for displays, or solar cell
- What is a doped semiconductor?
- Doped semiconductors are oxide semiconductor substrates (e.g., In 2 O 3, IZO, and IGZO) to which trace amounts of dopant are added, and the dopants are used to regulate and optimize the performance of semiconductor. Compared with other schemes, doped semiconductor only needs one deposition, which has the advantage of simple process.
- How to promote molecular doping of polymeric semiconductors?
- In principle, the efficient molecular doping of polymeric semiconductors can be promoted by introducing a thermodynamically favorable reaction via adding additives to turn the doping process into a designed coupled reaction. However, coupled reaction doping still lacks study for organic semiconductor doping in previous works.
- Which class of dopants increase Semiconductor mobility?
- 3) Electron donor doping, this class of dopants is mainly alkali metals, such as Na, K and so on. This class of dopants tends to give electrons and thus increase semiconductor mobility. 4) Rare earth doping, this kind of doping refers to Pr, La and other lanthanide metal oxide doping.
- Can coupled reactions improve the doping level of polymeric semiconductors?
- In addition to these recently reported methods, using coupled reactions is a theoretically promising way to improve the doping level of polymeric semiconductors with no need to increase the electron affinity of molecular dopants.
- How do strong bonding doping and electron donor doping affect semiconductors?
- In conclusion, the effect of strong bonding doping and electron donor doping on semiconductors is obvious. Strong bonding doping reduces V O and improves stability by forming a stable bonding structure with cations. Electron donor doping reduces V O while providing additional electrons to increase mobility.
- What is doping in TFT?
- Doping is a common method to optimize the stability of TFT. Doped semiconductors are oxide semiconductor substrates (e.g., In 2 O 3, IZO, and IGZO) to which trace amounts of dopant are added, and the dopants are used to regulate and optimize the performance of semiconductor.
