In intrinsic semiconductors the number of excited electrons and the number of holes are equal: n = p. This may be the case even after doping the semiconductor, though only if it is doped with both donors and acceptors equally. In this case, n = p still holds, and the semiconductor remains intrinsic, though doped.
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
According to Journal Citation Reports, the journal has a 2022 impact factor of 9.4. [1] PNAS is the second most cited scientific journal, with more than 1.9 million cumulative citations from 2008 to 2018. [2] In the past, PNAS has been described variously as "prestigious", [3] [4] "sedate", [5] "renowned" [6] and "high impact". [7]
The Journal of Biology was a peer-reviewed scientific journal published by BioMed Central. It was established in 2002 with the aim to provide an alternative to biology journals with high-impact factor such as Nature, Science, and Cell. Because of stringent selection criteria, it published only a few research articles per year, only four in 2007 ...
It was founded in 2000 and launched its first journal, PLOS Biology, in October 2003. As of 2024, PLOS publishes 14 academic journals, [2] including 7 journals indexed within the Science Citation Index Expanded, and consequently 7 journals ranked with an impact factor. PLOS journals are included in the Directory of Open Access Journals (DOAJ).
The wide intrinsic region makes the PIN diode an inferior rectifier (one typical function of a diode), but it makes it suitable for attenuators, fast switches, photodetectors, and high-voltage power electronics applications. The PIN photodiode was invented by Jun-Ichi Nishizawa and his colleagues in 1950. It is a semiconductor device.
A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
Wiley Interdisciplinary Reviews: Systems Biology and Medicine (abbreviated WIREs Systems Biology and Medicine) is a bimonthly peer-reviewed interdisciplinary scientific review journal covering systems biology and medicine. It was established in 2009 and is published by John Wiley & Sons as part of its Wiley Interdisciplinary Reviews journal
