INDIAN CIVIL SERVANT
Parameshwar Narain Haksar; P.N. Haksar; Purshottam Narayan Haksar; Purushottam Narayan Haksar; P N Haksar; PN Haksar; Parmeshwar Narayan Haksar
  • As [[Indira Gandhi]]'s (''pictured'') principal secretary, Haksar helped a beleaguered and inexperienced prime minister's rise to near-absolute power.

P. N. Haksar         
Parmeshwar Narayan Haksar (4 September 1913 – 25 November 1998) was an Indian bureaucrat and diplomat, best known for his two-year stint as Prime Minister Indira Gandhi's principal secretary (1971–73). In that role, Haksar was the chief strategist and policy adviser behind his inexperienced prime minister's rise to near-absolute power in the mid-1970s.
Pn junction         
  • A silicon p–n junction in reverse bias.
  • PN junction operation in forward-bias mode, showing reducing depletion width.
  • '''Figure B.''' A p–n junction in thermal equilibrium with zero-bias voltage applied. Under the junction, plots for the charge density, the electric field, and the voltage are reported. (The log concentration curves should actually be smoother, like the voltage.)
  • '''Figure A.''' A p–n junction in thermal equilibrium with zero-bias voltage applied. Electron and hole concentration are reported with blue and red lines, respectively. Gray regions are charge-neutral. Light-red zone is positively charged. Light-blue zone is negatively charged. The electric field is shown on the bottom, the electrostatic force on electrons and holes and the direction in which the diffusion tends to move electrons and holes. (The log concentration curves should actually be smoother with slope varying with field strength.)

A pn junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor. The "p" (positive) side contains an excess of holes, while the "n" (negative) side contains an excess of electrons in the outer shells of the electrically neutral atoms there.

P. N. Haksar

Parmeshwar Narayan Haksar (4 September 1913 – 25 November 1998) was an Indian bureaucrat and diplomat, best known for his two-year stint as Prime Minister Indira Gandhi's principal secretary (1971–73). In that role, Haksar was the chief strategist and policy adviser behind his inexperienced prime minister's rise to near-absolute power in the mid-1970s. After this he was appointed deputy chairman of the Planning Commission and then the first-ever chancellor of New Delhi's Jawaharlal Nehru University.

An advocate of centralisation and socialism, he was a Kashmiri Pandit who became Gandhi's closest confidant in her inner coterie of bureaucrats, the so-called "Kashmiri mafia". Prior to this, Haksar was a diplomat of the Indian Foreign Service, who served as India's ambassador to Austria and Nigeria.
