Adaptation kit Omicron

The adaptation kit for Omicron microscopes (AKOM4) interfaces the Nanonis controller with most types of Omicron microscopes.

Adaptation kit for Omicron SPMs

The original microscope cables connect directly to the pin-compatible interface, which makes it extremely simple to connect the control system to the microscope. The adaptation kit powers both STM and AFM pre-amplifiers and switches current and bias gains. In the case of beam deflection AFM models, the laser diode is monitored directly by the Nanonis software and the beam-deflection module displays the signals from the photo-detector. Control of inertial motors (x, y, z, mirrors and PSD) for coarse motion as well as automatic approach is seamlessly integrated in the Nanonis software and requires the Nanonis Piezo Motor Driver (PMD4).

Additionally, with the Nanonis OC4 add-on module, any dynamic AFM modes are available for all AFM models with either a regular cantilever, a qPlus sensor or a Needle Sensor.

Scanning Probe Microscopy are methods using a probe, that interacts with a surface producing high resolution images by surface scanning of the probe

Ultra-Low Current STM at 100fA

Ultra-Low Current STM at 100fA

Scanning at ever lower currents is an ongoing effort in the STM community. In a test run at the University of Lille, the Nanonis control system was put to test with an Omicron-1 STM to measure atomic resolution images on a Si-111 sample.

Needle Sensor Operation in non-contact AFM Mode

Needle Sensor Operation in non-contact AFM Mode

Needle sensors are becoming increasingly popular to measure the tunneling current while not depending on the current for the distance feedback. A resonance frequency of 1 MHz insures a fast response of the sensor while interacting with the surface, but it requires a highly accurate Phase Locked Loop (PLL) to perform non-contact AFM measurements, especially with low frequency shift set points.

Two dimensional quantum confinements at surfaces have always been a challenge for the scientists, mainly because of the difficulties to produce regular nanopatterns that can trap electronic states. One possibility of analyzing such structures is Scanning tunneling Microscopy (STM) and Spectroscopy (STS) at low temperature.

Supramolecular Rotary Device

For years a lot of efforts have been put on designing organic molecules whose properties can be exploited for building up artifi cial molecular devices. Together with our partners from the University of Basel and the ETH Zurich we created a specially functionalized molecule that on a Cu(111) surface does not only form a nanoporous network, but also have the right size to be nested on top of the pores.

Feenstra Type of Spectroscopy: Making use of the Programming Interface

Spectroscopic measurements in STM are an important tool for the investigation of the electronic states at surfaces. When combined with the variable tip-sample separation technique this type of spectroscopy leads to high dynamic range, 5 to 6 orders of magnitude, in the measured current and conductance even on the semiconductor surfaces with low surface state density.
