Three technological achievements related to the main fields of work, which are crystalline standards, self-assembling and DNA nano-origami, have been established during the first six months of the project.
First samples of crystalline step height standards have been successfully manufactured. These samples have, in addition to the atomic steps intended for step height certification, large atomically flat areas. This is important for a high precision alignment of the sample within AFMs during measurement. But these atomically flat areas are additionally serving as a known reference for the identification of the guiding errors of the tip movement in an x- and y-direction. With these samples the basic characterisation on metrological AFM instruments at different NMIs will be carried out. Furthermore the long term stability characterisation of these types of samples has now been initiated.
In the field of self-assembling structures, first samples have been successfully produced using block copolymers (BC) with a domain ordered structure, having regular spacing in each single domain. The pitch of these regular patterns is some ten nanometres. A second technological step toward the creation of lateral pitch standards, the transfer of these BC masks into Si crystals using reactive ion etching has been successfully demonstrated. The characterisation of these samples with appropriate AFM instrumentation will now provide feedback to optimise the production parameters.
Finally DNA nano-origami, with specifications tailored for AFM measurements, have been used for the production of 2D- and 3D objects as dimensional prototype standards for the nanotechnology. The resulting yield in production and the quality of the nano objects created are promising regarding for meeting the targets of this JRP.
