Материаловедение - одно из приоритетных направлений науки в Латвии. Институт физики твердого тела при Латвийском университете - лидер междисциплинарных исследований и исследований различных материалов в Латвии, имеющий признание и за рубежом. Основная цель исследований - создать базу для исследований материалов и проблем химии и физики твердого тела, делая уклон в область нанотехнологий, что позволило бы развивать высокие технологии уже в производстве страны. Чтобы достичь этой цели, необходимо сохранить и развивать человеческие и материальные ресурсы, включая инструментальную базу, экспериментальные ноу-хау, технологии, уже имеющихся специалистов и обучение молодых. Исследования в ИФТТ включают в себя электронные и ионные процессы в широкозонных полупроводниках с различной степенью упорядоченности; функциональные органические материалы и полимеры для фотоники и электроники; мультифункциональные и гибридные материалы для использования в энергетике: светодиоды, фотоэлектрические элементы и покрытия для солнечных панелей, хранение водорода для топливных элементов, электролиз и процессы в плазме для производства водорода, полимерные ионопроводящие мембраны для топливных элементов и разделения газов; неорганические монокристаллы, керамика, стекла, тонкие пленки и наноструктурированные материалы для применений в оптике, электронике, фотонике и энергетике.
Ключевые слова: материаловедение, нанотехнологии, материалы для энергетики.

One of the scientific priorities in Latvia is material science. The ISSP UL is an internationally recognized institution, a leader in the field of materials sciences and cross-disciplinary fields in Latvia. The main research objective of these cooperation projects is to build-up of a domestic research potential in the fields of material and solid state physics and chemistry with an emphasis on nanoscience that is a necessary condition for future high-tech industrial developments in the country. This task will be implemented by maintaining and further developing of both human and material research environment in Latvia, including instrumentation, experimental know-how, technologies, human work force and educational potential. The research of the ISSP includes electron and ion process in wide-gap materials with different degree of ordering; functional organic molecules and polymers for photonics and organic electronics; multifunctional and hybrid materials for energy applications: light emitting diodes, photovoltaic elements and coatings solar batteries, storage of hydrogen for fuel cell devices; electrolysis and plasma technologies for hydrogen production, polymer membranes with ionic conduction for fuel cells and gas separation; inorganic single crystals, ceramics, glasses, thin films, and nano-structured surfaces for application in optics, electronics, photonics and energetics.
Keywords: materials science, nanotechnologies, materials for energy.

History
The research in solid state physics at the University of Latvia restarted after World War II. The Institute of Solid State Physics (ISSP) of the University of Latvia was established on the basis of Laboratory of Semiconductor Research and Laboratory of Ferro- and Piezoelectric Material Research in 1978. Since 1986 the ISSP has the status of an independent organization of the University and now is the main material science institute in Latvia.
Four laboratories from the Institute of Physics of the Latvian Academy of Sciences joined our Institute in 1995. Twenty scientists of the former Nuclear Research Centre joined the ISSP in 1999 and established Laboratory of Radiation Physics. In 2004 scientists from the Institute of Physical Energetics joined ISSP and established Laboratory of Organic Materials. In mid 90-ties the ISSP has intensified its teaching activities. A number of researchers have been elected as professors of the University of Latvia. Post-graduate and graduate curricula were offered in solid state physics, material physics, chemical physics, physics of condensed matter, semiconductor physics, solid state ion conducting materials and experimental methods and instruments. In 2002 the Chair of Solid State and Material Physics University of Latvia was established at ISSP.
Research and training in optometry and vision science is taking place in the Laboratory of Visual Perception of the ISSP since 1992. Co-located with the Institute, the Optometry Centre has been established in 1995 with facilities for primary eye care and serving as a technological research basis for students and staff.
In December 2000 the ISSP was awarded the Centre of Excellence of the European Commission (Centre of Excellence for Advanced Material Research and Technologies). This honorary recognition with the accompanying financial support of 0,7 million EUR has increased our research activities, particularly extending the list of our research partners and scientists who come to work to our Institute from the leading European research centers.
The highest decision-making body of the ISSP is the Scientific Council of 22 members elected by the employees of the Institute. The International Supervisory Board of ISSP LU was established in 1999. It consists of 17 members representing Europe, Russia, USA and Japan and being selected from distinguished scientists in the field of material sciences.
Nowadays ISSP UL staff includes 105 academic personnel: 78 researchers with Dr. habil., and Dr. degrees, 27 PhD students and 22 bachelor and master students, though the number of students are changing year by year.
Laboratory of Hydrogen energy materials was founded on 2005 as part from Solid state ionic Laboratory. Fast ion transport and intercalation properties in different transition metal oxides were studied from middle of 1970ies in connection with electrochromic phenomena and gas sensing properties.
