[edit] Goals
The Laboratory of Nano and Quantum Engineering (LNQE) is an interdisciplinary research center of the Leibniz Universität Hannover in the field of nanotechnology. Substantive goals are both excellent basic research as well as application-oriented engineering at the nanoscale accompanied by appropriate cross-disciplinary training. To achieve its objectives the LNQE has its own research building in Hanover, with laboratories, equipment, etc., and especially clean rooms.
[edit] Members
The LNQE comprises 29 work groups from natural science and engineering of the Leibniz University of Hanover. It is lead at least by an executive board of four members which nominate a speaker from their middle. The executive board is supported by the LNQE-Office.

[edit] Research
The collective term nanotechnology describes the study and manipulation of objects at smallest sizes. In general, the nanotechnology deals with structures ranging in size from 1-100 nanometers in at least one spatial direction. 100 nanometers are roughly one-thousandth of the diameter of a normal human hair. With these small dimensions surface properties come to the fore compared with the bulk properties of materials and also often quantum effects has to be taken into account. Nanotechnology is the technology of small things with new features and functionalities.
Nano engineering is the engineering on the nanoscale, i.e., the selective artificial fabrication of nanotechnology structures such as tiny transistors on computer chips. The with nano engineering closely related term quantum engineering aims to produce and manipulate a defined quantum state, such as the realization of a Bose-Einstein condensate or a electronic device with adjusted electron spin. The size of such systems is also often in the nanometer range.
Nanomaterials of various shapes, composition and size in the nanometer range are produced and analyzed in the laboratory. Nanoparticles have due to their small size special chemical and physical properties that differ significantly from the properties of macroscopic particles and solids. The cause therefore is the large ratio of surface to volume of the nanoparticles, so that they strongly interact with their environment. Added where appropriate quantum mechanical effects.
The structure size of electrical devices on a computer chip are much smaller than 100 nanometers today. The construction of the structures remained almost unchanged in recent years, only the structure size was reduced gradually in the different technology generations. Processor technology with dimensions of 25 nanometers are already used today. It is assumed for quite some time, that this constantly scaling will encounter its physical limits very soon. Therefore new, revolutionary concepts are explored to reduce the feature size further.
[edit] Education
Activities in education:
- Colloquium series
- Workshop NanoDay: a one-day workshop, which shows the broad spectrum of nanotechnology of the LNQE with talks and a poster session. This annual event takes place since 2005.
- Study course nanotechnology: bachelor course beginning at winter semester 2008 at the University of Hanover, master course from 2011.
[edit] Scientific New Build LNQE
The scientific new build stands in the middle of the Nordstadt, the university area of Hanover/Germany, at Schneiderberg 38, 30167 Hannover, Germany. The scientific building has 430 sqm of chemical, measurement and laser laboratories. 410 sqm are a research clean room and 509 sqm are workrooms for 44 staff members. The costs are approx. 14 Mio Euros. After successful evaluation by the German Wissenschaftsrat it gets federal grants. The project management was does by public project management Hannover, the planning was done by the architecture office KSP Jürgen Engel. The building was opened in November 2009.
