Algis Jurgis Kundrotas (July 15, 1950, Užšustis, Šilutė district, Lithuania)[A] is a Lithuanian physicist, habilitated doctor of physical sciences, university professor and independent researcher.[2]

Life[edit]

Undergraduate Education[edit]

Vilnius Pedagogical Institute from 1968 to 1972, where he completed his university studies in 1972 (diploma in physics cum laude; su pagyrimu lot).[2]

Postgraduate Education[edit]

He completed his subsequent studies in Vilnius at the Semiconductor Physics Institute from 1976 to 1979. He became candidate of physical and mathematical sciences (Doctor of Natural Sciences; Ph.D. degree) in 1981, when he defended his dissertation at Vilnius University (thesis on: Investigation of kinetic processes in narrow gap semiconductor PtSb2). He became a Doctor of Physical Sciences (Dr. Habil. of Physical Sciences, Physics; DrSc. degree - physics) in Vilnius Semiconductor Physics Institute in 1999 (thesis on: Impact ionisation of shallow impurities and excitons in A3B5 semiconductors and quantum wells).[2]

Professional Experience[edit]

From 1980 to 2015, Algis Jurgis Kundrotas worked at the Semiconductor Physics Institute,[B] where he progressed through various positions. Between 1980 and 1986 as a Junior Research Associate, followed by a two-year period (1986–1987) as a Research Associate. From 1987 to 2000 he held the position of Senior Research Associate. In 2001 he was appointed as Chief Researcher and Algis Jurgis Kundrotas remained in this position until 2010. From 2010 until the end of his career in 2015, A. J. Kundrotas was a Senior Researcher at the Semiconductor Physics Institute of Center for Physical Sciences and Technology (FTMC).[2]

Moreover, he started his university teaching career (with the title of university professor) in 2002 at Gediminas Technical University in Vilnius, Lithuania,[2] where he was employed at the Physics Department from 2002 to 2015. He lectured in the field of mathematical modelling of physical processes for Master's students. From 2009 he was Certificated Professor of physical sciences of the Vilnius Gediminas’ Technical University and the title is valid all time from the time of Certification. From finishing professional scientific career in 2015 up to at present he has been working as an independent scientific researcher.

A. J. Kundrotas and the Lithuanian Revival Process[edit]

In 1988, a civic movement known as Sąjūdis - the Lithuanian Reconstruction Movement - began to emerge in Lithuania. Its first goal was to achieve genuine Lithuanian autonomy within then Soviet Union, but eventually the movement's goals grew to include the pursuit of full Lithuanian independence.

Prior to the founding meeting of the members of Sąjūdis, a meeting was held at the Lithuanian Academy of Sciences, which was attended by Professor Adolfas Dargys and Jurgis Kundrotas as representatives of the Institute of Semiconductor Physics.[4] A meeting of research institute staff was held at the Lithuanian Academy of Sciences on 15 February 1988. Here a declaration was adopted demanding the abolition of the Molotov-Ribbentrop Pact, recognition of the illegality of Lithuania's incorporation into the USSR, and the restoration of Lithuania as a sovereign state. Jurgis Kundrotas was also responsible for signing the declaration.[4] It is therefore not surprising that the most important centres of the Sąjūdis movement in Vilnius at that time were the Institutes of Semiconductor Physics and Physics. Here they raised money, sewed flags, painted posters, prepared important documents, such as proposals for a constitution, for the introduction of the presidency, etc.[4]

During these revival processes, the Lithuanian Union of Scientists was founded, which was one of the most influential organisations. Jurgis Kundrotas was the head of the secretariat of the Lithuanian Union of Scientists and the editor-in-chief of the newspaper Mokslo Lietuva (Lithuanian Science).[4] This publication had a circulation of 5,000 copies, and its supplement for English language students "Step by Step" had a circulation of 35,000 copies.[4]

Lithuania achieved full independence on 11 March 1990, thanks to Vytautas Landsbergis' initiative, when the Supreme Soviet of the Lithuanian Soviet Socialist Republic proclaimed the Law on the Restoration of the Independent State of Lithuania. Lithuania did not achieve real independence until after 21 August 1991.

Awards[edit]

Lithuanian National Award in Science (2000). In March 2001, Jurgis Kundrotas and his colleagues (Professor Adolf Dargis and Dr. Neria Žurauskienė) were awarded the National Award for Merit in Physical Sciences for the year 2000 for the series of papers Shock and Tunnel Ionization in Semiconductors.[4][2]

Notes[edit]

  1. ^ In the Lithuanian Wikipedia the village where Jurgis Kundrotas was born is called Užšuščiai, but according to the Czech map documentation (Mapy cz) it is the village "Užšustis" consisting of two sets of buildings (two solitudes separated by a forest belt about 80 metres wide are each made up of a few houses). The name "Užšustis" means in Lithuanian "behind the river Šustis", which flows about 150 metres south of the northernmost object of the village (and about 50 metres south of the southernmost object of the village). The river Šustis in its last third flows in an approximately east-west direction and south of the village of "Užšustis" forms a northward-running semicircular arc with a radius of 120 metres. The exact place of birth is an object at GPS coordinates 55.3593942N, 21.6828003E (55°21'33.819 "N, 21°40'58.081 "E). The village of "Užšustis" is located about 1.5 kilometres west of the town of Žemaičių Naumiestis (Žemaičių Naumiestis Eldership, the town of Šilutė District) in western Lithuania (about 32 km east of the coast of the Gulf of Curonian Spit)[1]
  2. ^ The Semiconductor Physics Institute (abbreviated as PFI) was a Lithuanian research institute that operated from 1967 to 2010, conducting research and experimental development in the fields of physics, electronics, materials science, high technology and primary metrology. It participated in joint projects with Lithuanian enterprises and supported the development of the high-tech industry. In 2010, the institution was merged with the Institute of Physics and Chemistry to form the Centre for Physical and Technological Sciences.
