SOLID-STATE PHYSICS RESEARCH INFRASTRUCTURE GROUP

Presentation of the RI group
The knowledge and theoretical description of the atomic structure, optical, transport and magnetic properties of ma-
terials are essential both for our fundamental scientific understanding and for modern technologies. The experimental
and theoretical examination of these properties is the task of solid-state physics. The laboratories of the consortium
produce and investigate materials that are currently the most interesting for exploratory research. Atomic structures
are determined with modern X-ray diffractometers (MTA Wigner FK, MTA EK MFA) and scanning methods, such
as atomic force, tunneling and electron microscopy, as well as transmission electron microscopy and electron holography
(MTA EK MFA, MTA Wigner FK, BME, PE). In addition to the traditional methods, some laboratories are developing
new measurement techniques, such as X-ray holography or single molecule mapping based on modern free-electron
X-ray sources (MTA Wigner FK). In addition to structure characterization, the infrastructure enables the determination
of transport and magnetic properties in a wide temperature range and the performance of quantum transport experi-
ments at ultralow (4mK >) temperatures (BME). These investigations are supported by a variety of resonance methods,
such as electron spin resonance (ESR, BME), nuclear magnetic resonance (NMR, BME), or optically detected magnetic
resonance (ODMR, BME). Optical parameters can be examined with vibrational spectroscopy (infrared and Raman
spectroscopy; MTA Wigner FK) and magneto-optical experiments from THz to UV (BME). The properties of electron
structure are examined with X-ray spectroscopy (MTA Wigner FK) in the laboratories. In addition to the determination
of material properties, it is also very important that research groups have the opportunity to produce samples at their
own initiative. To this end, each laboratory is specialiing in different material synthesis techniques. So, there is a synthetic
chemistry laboratory specialising in the production of small-molecule organic and inorganic compounds (MTA Wigner
FC), and laboratories specialising in the production of thin films (MTA Wigner FK, MTA EK MFA, BME). These
allow the production of a variety of materials and structures from high-temperature superconductors, fullerenes and
carbon nanotubes to graphene, metal-organic framework (MOF) structures and other nanostructures and nanoelec-
tronic circuits. Materials that cannot be produced in domestic laboratories can be studied in the framework of joint
collaborative projects with foreign partners. In addition to experimental equipment, the computational background
plays an increasingly important role. It is essential both for the evaluation of measurements and for the theoretical pre-
diction of material properties. Depending on the given task, the laboratories use central large computing systems (e.g.
Wigner Cloud) or local computer capacity supervised by them (MTA Wigner FK, SZFI, BME).

Aim of the RI group
Status of the RI group: operating The most important tasks for the upcoming period include the
further development of the research infrastructure, the mainte-
nance and further development of the high-level of human re-
sources, preparation for using the large domestic and international
infrastructures under construction, and enhancing the capacity of
utilisation of existing RIs.
