- Definition(s)
- A material that is intentionally added to a pure semiconductor material to increase the population of free holes in that semiconductor, resulting in a net positive charge. A semiconductor that has had acceptor material added to it is called "p-type." Tyco Electronics Corporation - by Enrique Cavalitto
- Example sentence(s)
- For practical doping levels, it is fair to assume that the free electron concentration is equal to the concentration of donor atoms and the hole concentration is equal to the concentration of acceptor atoms. - everything2.com
by Enrique Cavalitto - Acceptor dopant in nitride semiconductors makes deep acceptor level (>100 meV) and generates few hole carriers into the valence band because of large electron affinity of N. - Materials Research Society
by Enrique Cavalitto - The energy gained when an electron is taken up by an acceptor atom from the valence band of the crystal is the ionization energy of the atom. - answers.com

- Un accepteur (d’électrons) est une impureté ajoutée en quantité déterminée à un matériau semiconducteur pour en augmenter la population de trous, avec pour effet une charge nette positive. Un semiconducteur contenant des atomes accepteurs est dit de type « p ». Own research - by Philippe Etienne

- akceptor (akceptorska primesa)
- Additional fields of expertise
- Definition(s)
- Primese unose nove energetske nivoe u zabranjenu zonu i time značajno utiču na provodnost poluprovodnika. Poluprovodnici u kojima se elektroni i šupljine stvaraju u paru nazivaju se intrinsični (unutarnji) poluprovodnici. Takvi poluprovodnici su samo ako je materijal čist (bez primesa). Poluprovodnici u kojima ima i primesa nazivaju se ekstrinsični (spoljni) poluprovodnici.
U poluprovodniku s primesama postoje slobodni nosioci elektriciteta (elektroni i šupljine) i vezani nosioci elektriciteta: joni primesa (negativni akceptori i pozitivni donori). Own research - by V&M Stanković
- Example sentence(s)
- Ako se silicijumu doda mala količina primesa od materijala koji ima tri valentna elektrona (bor, indijum, ili drugi elementi 3. grupe), pojaviće se višak šupljina, koji takođe povećava provodnost silicijuma. Takve primese se nazivaju akceptorske primese jer privlače (primaju) slobodne elektrone, a tako dopirani silicijum se naziva p-tip silicijuma, jer ima više slobodnih nosilaca pozitivnog naelektrisanja (šupljina) nego elektrona. - Elektrotehnički fakultet u Beogradu
by V&M Stanković - Kod poluprovdnika p-tipa dodali smo akceptorske primese. Akceptorska primesa ima manjak eletrona tako da ona generiše šupljinu i na taj način se stvara višak šupljina tj pozitivnih naelektrisanja u poluprovdniku. Kod počuprvodnika p-tipa šupljine predstavljaju većinske nosioce naelektrisanja a elektroni manjinske nosice. - Vikipedija
by V&M Stanković - Donor – atom nečistoće koji povećava koncentraciju elektrona, dopant n-tipa.
Akceptor –atom nečistoće koji povećava koncentraciju šupljina, dopant p-tipa. - Fakultet tehničkih nauka, Novi Sad

- Definition(s)
- 在固态物理学中,受体是把一些物质参杂在半导体里,而让它变成p型半导体。
硼原子当作受体参杂在硅原子里。比方说,当再有四个价电子的硅原子里面参杂只有三个价电子的铝或硼会再硅晶格里形成一个空洞,这些空洞会吸引其他地方的电子,而产生电流,这就形成了p型半导体。

- Definition(s)
- L'utilizzazione dei semiconduttori nei dispositivi elettronici richiede la preparazione di materiali estremamente puri che possano essere drogati con quantità minime e rigorosamente controllate di atomi donatori o accettori di elettroni De Agostini - Sapere.it - by Simona Corsellini
- Example sentence(s)
- Un transistor bipolare è costituito da tre zone drogate separate da due giunzioni. Nella versione n-p-n, un sottile strato drogato con atomi accettori è interposto tra due zone di tipo n - CNR
by Simona Corsellini - Siano ND,NA le concentrazioni di impurezze rispettivamente degli atomi pentavalenti e trivalenti: esse sono il numero di atomi droganti per metro cubo immessi nel semiconduttore, D sta a significare che gli atomi sono donatori cioè forniscono elettroni, A che sono accettori cioè forniscono lacune. In un semiconduttore tipo n - Wikipedia
by Simona Corsellini - Se il drogante ha solo tre elettroni di valenza, il legame covalente è incompleto e nel reticolo cristallino genera una lacuna: il drogante si dice “accettatore” o “accettore” (dall’inglese acceptor) e il semiconduttore drogato è detto di tipo p, poiché in esso prevalgono portatori di carica positivi (le lacune). - Encarta
