'''Ernest Arushanov''' ({{lang|ru|Эрнест Константинович Арушанов}}; born February 4, 1941) is a Soviet and Moldovan experimental physicist, academician of the Academy of Sciences of Moldova.

==Biography== He was born and raised in Baku, where he graduated from high school in 1958.<ref name=bio>[http://www.asm.md/index.php?go=detalii-membri&n=17&new_language=0 Ernest Arushanov's biography at the website of the Academy of Sciences of Moldova]</ref> Immediately after graduating from high school arrived in Chișinău, where he entered Kishinev State University (Moldova State University now), Physics and Mathematics department. In 1963 after successful graduation from the university he entered the post-graduate department of the same university, resulted in the PhD thesis in the field of semiconductor compounds<ref name=candit>Автореферат диссертации на звание кандидата в доктора физико-математических наук. — Кишинев: Штиинца, 1968 год. — С.48.</ref> (1969). In the period from 1967 to 1986, he worked as a researcher at the Institute of Applied Physics, Academy of Sciences of the Moldavian SSR, in the laboratory of Sergei Ivanovich Radautsan.<ref>{{Cite web |url=http://www.radautan.info/ |title=Sergei Ivanovich Radautsan's biographi |access-date=2011-01-25 |archive-url=https://web.archive.org/web/20110721231722/http://www.radautan.info/ |archive-date=2011-07-21 |url-status=dead }}</ref> Then in 1984, defended his doctor-habilitat dissertation.<ref name=doct>Автореферат диссертации на звание доктора физико-математических наук. — Кишинев: Штиинца, 1983 год. — С.56.</ref> From 1986 to 1988 – he was head of the laboratory he created - Laboratory of the narrow-gap materials. In 1988 he was appointed the deputy director of the Institute of Applied Physics. In 1989 Arushanov became professor, and in 1992 he was elected a Corresponding member of the Academy of Sciences of Moldova.<ref name=bio />

After the collapse of the Soviet Union, Arushanov made a substantial contribution to the preservation of the Institute's capacity, attracting foreign investments for further development of Moldovan science in general and for physics development in particular. In 1997, he resigned as deputy director and became the head of Laboratory of Materials and Structures for Solar Energy Conversion.

In 2000, at a general meeting of the Assembly of the Academy of Sciences of Moldova, Arushanov was elected Academician.<ref name=bio />

Arushanov has more than 40 years.<ref name=acad1>Academia de Stiinte a Republicii Moldova-50. — Chişinău, 1996. — P.135-136.</ref> The first course in semiconductor physics, he lectured at the Kishinev Polytechnic Institute, named after Sergey Lazo in the period from 1970 to 1972. Later in the same place, Arushanov lectured on Materials and Semiconductor Physics (1986–1988).

The collapse of the Soviet Union gave Soviet professors and researchers the opportunity to work in the West; Arushanov took advantage of it. In 1993–1994, he held seminars on physics at the University of Konstanz, Germany. This was followed by an invitation to France, where Arushanov was offered to lecture physics, first in 1995 and 1996 at the Paul Sabatier University in Toulouse, and then in 2002 at the University of Paris. Also Ernest Arushanov in different periods lectured as an invited professor at specialized Institutes and Universities<ref name=acad2>Academia de Stiinte a Moldovei. Academy of Sciences of Moldova. — Chișinău, 2001. — P.100.</ref> of Austria, England, Holland, Spain, Canada, Poland, Singapore, and Switzerland.

Since 1974, Arushanov prepared 15 PhDs, and continues to pass his knowledge to present graduate students.

E. Arushanov's scientific interests are extremely diverse, but still the bases of his works are works on the theory of transport phenomena in various semiconductor compounds. This is evidenced by his dissertations, PhD and doctorate.

PhD thesis of E. Arushanov "Investigation of transport properties in single crystals of cadmium antimonide"<ref name=candit /> was written during the work in the laboratories of the Kishinev State University and the Ioffe Physical Technical Institute (Leningrad). His doctoral advisor was one of the best professors KSU, lecturer and PhD in Physics and Mathematics, Ivan Andronic. One of the official opponents was the future academician of three Academies (New York, Azerbaijan and the International Academy of Ecoenergetics) and well-known scientist in the field of semiconductor physics Maksud Aliev,<ref>[http://www.science.az/ru/acmembers/aliyevmkir.htm M. I.

The second opponent on doctoral thesis was the State Prize of the USSR laureate, Doctor of Physical and Mathematical Sciences Professor Anatolii Regel.<ref>[http://www.ioffe.ru/LLT-SH/Regel-eng.html Anatoli Robertovich Regel (1915—1989)// FTP, 29(5), 1995]</ref> 180px|thumb|Ernest Arushanov during the work with intense magnetic fields. Doctoral dissertation of Ernest Arushanov began a new research direction in physics and materials science of semiconductors – the growth of single crystals, determination of the band structure, scattering mechanisms of charge carriers and the practical application of semiconductors A²₃B⁵₂ and A²B⁵ based on cadmium[4].

During his research EK Arushanov obtained 12 patents, has published three monographs, three reviews and more than 300 scientific articles<ref name=acad2 /> in various national and international journals, on crystal growth, electrical, optical and magnetic properties of materials for solar energy, thermoelectricity, optoelectronics, spintronics and superconductors. At the present time, the main scientific interest of Ernest Konstantinovich is finding new absorbing materials for solar cells, which he does successfully in the Laboratory of Materials and Structures for Solar Energy Conversion. However, being a famous scientist in the field of semiconductor compounds properties investigation, Ernest Arushanov is a frequent guest in the laboratories of various countries (including Germany, Spain, France and many others), where he is engaged in completely diverse studies.

==Awards== *State Prize of Moldavian SSR in the Field of Science and Technique for work on Material Science and Physics of Semiconductors<ref name=acad1 /> (1983). *State Prize of Republic of Moldova in the Field of Science and Technique for work on Ternary and Multinary compounds<ref name=acad2 /> (1998). *In 2001, Ernest Arushanov became «Om Emerit» for achievements in the development of Moldovan science.
