Laboratory of Molecular Beam Epitaxy (MBE)


Molecular Beam Epitaxy (MBE) is a crystal growth technique that is performed under ultra-high vacuum conditions on a monocrystalline substrate at a very low deposition rate, typically below one monolayer per second. We utilize MBE to grow various semiconductor heterostructures, including thin layers, quantum wells, quantum dots, nanowires, microcavities, diluted magnetic semiconductors, topological semimetals, and transition metal dichalcogenides (TMDs).

Our MBE machine consists of two growth chambers:
II-VI chamber for tellurides and selenides, including TMDs.
III-V chamber for arsenides, including TaAs.

Our team in 2024:
Prof. Wojciech Pacuski - head of the lab.
Prof. Janusz Sadowski - part time coworker, advisor.
Dr. Michał Grzybowski - PI of independent project.
Dr. Karolina Połczyńska - now on sabbatical at DTU .
Mgr. Julia Kucharek - PhD candidate.
Lic. Adam Szczerba - Mgr. candidate.
Lic. Blanka Tronowicz.

MBE Team in 2021: Julia Kucharek, Janusz Sadowski, Wojciech Pacuski, Bartłomiej Seredyński, Karolina Połczyńska.
Creator: Aleksander Rodek.

The laboratory was established in 2010 by Dr. Tomasz Słupiński and Dr. Wojciech Pacuski as part of the Center for Preclinical Research and Technology (CePT) at the Solid State Physics Division, Institute of Experimental Physics, Faculty of Physics, University of Warsaw. Since 2014, the laboratory has been housed in Cent I building (room 1.222). Now, Wojciech Pacuski serves as the head of the laboratory, Tomasz Słupiński works in MBE lab in IFPAN .

Among our achievements is a recipe for growth of high optical quality TMD monolayers using hBN substrate [51,58,69], the first epitaxial growth of topological semimetals TaAs [65,74] and NiTe2 [57], the first observation of a QD with a single Co ion [16,35] and with a single Fe ion [26,32], and farbication of semimagnetic microcavites with amazing magnetooptical properties [7,15,20,27,34,37,39,43,53,55,56,62,64,67,71,73]. The list of our publications is provided below. For more updates, you can follow us on Twitter or visit the website of coworking Laboratory of Ultrafast MagnetoSpectroscopy (LUMS). Below there are also graphics produced to advertise our research.
