  2. Acceptor (semiconductors) - Wikipedia

    en.wikipedia.org/wiki/Acceptor_(semiconductors)

    In semiconductor physics, an acceptor is a dopant atom that when substituted into a semiconductor lattice forms a p-type region. Boron atom acting as an acceptor in the simplified 2D silicon lattice. When silicon (Si), having four valence electrons , is doped with elements from group III of the periodic table , such as boron (B) and aluminium ...

  3. p-value - Wikipedia

    en.wikipedia.org/wiki/P-value

    Thus computing a p-value requires a null hypothesis, a test statistic (together with deciding whether the researcher is performing a one-tailed test or a two-tailed test), and data. Even though computing the test statistic on given data may be easy, computing the sampling distribution under the null hypothesis, and then computing its cumulative ...

  4. Doping (semiconductor) - Wikipedia

    en.wikipedia.org/wiki/Doping_(semiconductor)

    Doping of a pure silicon array. Silicon based intrinsic semiconductor becomes extrinsic when impurities such as Boron and Antimony are introduced.. 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.

  5. Master's degree - Wikipedia

    en.wikipedia.org/wiki/Master's_degree

    A Master of Science degree conferred by Columbia University, US. A master's degree [note 1] (from Latin magister) is a postgraduate academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice.

  6. Voiceless bilabial plosive - Wikipedia

    en.wikipedia.org/wiki/Voiceless_bilabial_plosive

    Features of the voiceless bilabial plosive: Its manner of articulation is occlusive, which means it is produced by obstructing airflow in the vocal tract.Since the consonant is also oral, with no nasal outlet, the airflow is blocked entirely, and the consonant is a plosive.

  7. Systole - Wikipedia

    en.wikipedia.org/wiki/Systole

    Electrical waves track a systole (a contraction) of the heart. The end-point of the P wave depolarization is the start-point of the atrial stage of systole. The ventricular stage of systole begins at the R peak of the QRS wave complex; the T wave indicates the end of ventricular contraction, after which ventricular relaxation (ventricular diastole) begins.

    The Pratt & Whitney Canada PT6 is a turboprop aircraft engine produced by Pratt & Whitney Canada.Its design was started in 1958, it first ran in February 1960, first flew on 30 May 1961, entered service in 1964, and has been continuously updated since.

  9. Acetone - Wikipedia

    en.wikipedia.org/wiki/Acetone

    Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
