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.
Doping in III-V Semiconductors - Cambridge Core
The author describes in detail all the various techniques, including doping during epitaxial growth, doping by implantation, and doping by diffusion. The key characteristics of all dopants that have been employed in III–V semiconductors are discussed.
Surface Transfer Doping of Semiconductors | Science
It is only through doping that semiconductors become useful electronic materials. Recent studies have revealed an unconventional way to achieve doping through surface engineering. Doping of semiconductors is usually achieved by incorporating atoms of appropriate elements into the host lattice of the semiconductor.
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
- What is semiconductor doping?
- A precise and reproducible method of semiconductor doping in which selected dopants are ionized and accelerated at high velocity to penetrate the semiconductor substrate and become deposited below the surface. You might find these chapters and articles relevant to this topic. Magno B. Costa, ... Lucia H. Mascaro
- What happens if a semiconductor is doped?
- In most cases many types of impurities will be present in the resultant doped semiconductor. If an equal number of donors and acceptors are present in the semiconductor, the extra core electrons provided by the former will be used to satisfy the broken bonds due to the latter, so that doping produces no free carriers of either type.
- How does p-type doping work?
- For effective dopants, this energy is rather small. At room temperature, it is easily supplied by the vibrations of the semiconductor atoms, and one ends up with free charge carriers of one sign and fixed ionized dopants with opposite charge. This situation is sketched for p-type doping in the figure (left panel).
- What materials are used for doping?
- Other materials are aluminum, indium (3-valent) and arsenic, antimony (5-valent). The dopant is integrated into the lattice structure of the semiconductor crystal, the number of outer electrons define the type of doping. Elements with 3 valence electrons are used for p-type doping, 5-valued elements for n-doping.
- What is doping a semiconductor with metallic/non-metallic elements?
- Doping a semiconductor with metallic/non-metallic elements is a strategy used to manipulate its optical and electronic properties, and tailor its band structure [4,35].
- What is Monolayer doping?
- The doping of semiconductor materials plays a crucial role in tuning electrical properties. Monolayer doping (MLD) is an alternative technique for doping semiconductors utilizing dopant-containing organic molecules and their grafting onto semiconductor surfaces.
