Semiconductor deviceA semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor devices have replaced vacuum tubes in most applications. They conduct electric current in the solid state, rather than as free electrons across a vacuum (typically liberated by thermionic emission) or as free electrons and ions through an ionized gas.
Orbital angular momentum of lightThe orbital angular momentum of light (OAM) is the component of angular momentum of a light beam that is dependent on the field spatial distribution, and not on the polarization. It can be further split into an internal and an external OAM. The internal OAM is an origin-independent angular momentum of a light beam that can be associated with a helical or twisted wavefront. The external OAM is the origin-dependent angular momentum that can be obtained as cross product of the light beam position (center of the beam) and its total linear momentum.
Creative writingCreative writing is any writing that goes outside the bounds of normal professional, journalistic, academic, or technical forms of literature, typically identified by an emphasis on narrative craft, character development, and the use of literary tropes or with various traditions of poetry and poetics. Due to the looseness of the definition, it is possible for writing such as feature stories to be considered creative writing, even though it falls under journalism, because the content of features is specifically focused on narrative and character development.
Fiction writingFiction writing is the composition of non-factual prose texts. Fictional writing often is produced as a story meant to entertain or convey an author's point of view. The result of this may be a short story, novel, novella, screenplay, or drama, which are all types (though not the only types) of fictional writing styles. Different types of authors practice fictional writing, including novelists, playwrights, short story writers, radio dramatists and screenwriters. Fiction#Categories of fiction A genre is the subject matter or category that writers use.
