Neutron Transmutation Doping of Silicon | MIT Nuclear Reactor Laboratory
The NTD process takes place when undoped (high purity) silicon is irradiated in a thermal neutron flux. The purpose of semiconductor doping is to create free electrons (low resistivity). The thermal neutron is captured by the 30Si atom, which has a 3% abundance in pure Si.

The United States must increase its domestic capacity for high-purity minerals, gases, and chemicals, or else American semiconductor capacity—and national security—will remain highly...
Doping Approaches for Organic Semiconductors | Chemical Reviews
Electronic doping in organic materials has remained an elusive concept for several decades. It drew considerable attention in the early days in the quest for organic materials with high electrical conductivity, paving the way for the pioneering work on pristine organic semiconductors (OSCs) and their eventual use in a plethora of applications. Despite this early trend, however, recent strides
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.
- What is a doped semiconductor?
- In semiconductor production, doping is the intentional introduction of impurities into an intrinsic (undoped) semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor.
- What are ultra high purity materials?
- We provide an ever-evolving portfolio of Ultra High Purity materials to meet current and future process needs for deposition, etching and doping of semiconductor device layers. We are a leading supplier of ultra high purity gases including halocarbons, hydrocarbons and other reactive gases also named as electronic specialty gases (ESGs).
- How does doping affect a semiconductor?
- Doping a semiconductor in a good crystal introduces allowed energy states within the band gap, but very close to the energy band that corresponds to the dopant type. In other words, electron donor impurities create states near the conduction band while electron acceptor impurities create states near the valence band.
- Is no doping a promising technique for advancing p-type 2D transistors?
- Our findings establish NO doping as a promising technique for realizing high-performance p-type 2D transistors and advancing next-generation ultra-scaled electronic devices. 2D semiconductors are promising candidates for next-generation electronics, but the realization of competitive 2D p-type transistors remains challenging.
- Is no doping a universal p-type doping method for low-dimensional materials?
- More detailed characteristics can be found in our previous work, where the combination of work function engineering and NO p-doping are adopted to achieve high-performance inverters based on few-layer MoTe 2 70. These results show that NO doping is a relatively universal p-type doping method for low-dimensional materials.
- Do nitric oxide dopants introduce a doping band near the mid-gap region?
- The presence of nitric oxide dopants introduces an acceptor doping band near the mid-gap region. Insets show the corresponding atomic structures obtained from density functional theory (DFT) calculations. c Schematic density of states (DOS) plots of the doping impact as extracted from a and b.
