Filter configuration tool
The filter configuration tool makes it easy to determine suitable time constants and filter slopes based on the required integration time. It also displays frequency and step response
Transfer Function measurement
Transfer functions of the signal chain can easily be measured with the transfer function tool

The lock-in detectors let you modulate and demodulate any of the input and output signals of Nanonis Tramea™ with a frequency up to 40 kHz and making use of the high resolution and high precision 20-bit outputs. With the multi-frequency option a single module can demodulate up to 8 harmonics of the same signal or independent input signals. Up to 8 lock-in detector modules can be used independently from each other when the generation of multiple frequencies is required. The advantage of an internal lock-in detector over an external device is 

  • Higher resolution and dynamic range
  • Multifrequency and multi-input operation
  • Over 120 dB linearity
  • Over 100 dB dynamic reserve
  • No need for gain and attenuation switching
  • Steeper filters (up to 8. order) 
  • Up to 8 independent modules
  • Synchronization with data acquisition when using Sync filtering
  • Integration avoids errors due to insufficient settling time with slow filter responses 
  • no additional noise source through external cabling
  • no potential grounding problems
  • flexible and simple setup
  • Guided filter set-up utility
  • Ability to turn on and off the excitation through software during the experiment

Applications range from regular transport measurements to multi-terminal Hall measurements, multifrequency measurements, simultaneous data acquisition with different time constants, dI/dV, inelastic electron tunneling spectroscopy (IETS), measurements of open and closed loop transfer functions and every type of phase sensitive measurements.

APPLICATION NOTES

Topological Insulator Josephson junctions
Topological Insulator Josephson junctions
In a topological insulator (TI), the electronic structure of the bulk reveals a unique topology that leads to the formation of conducting surface states with intriguing properties. The topological protection of the surface states and the possible emergence of Majorana fermions in superconductor/TI hybrid devices make these materials a leading candidate for use as a robust platform for future fault-tolerant quantum computation. The main challenge in creating these structures lies in the fabrication of an electrically transparent interface between the conventional superconductor and the topological insulator. A Josephson junction, formed by two closely spaced superconducting electrodes separated by a gap of less than 100 nm, can be used as a measure of the quality of the electrical interface. At low temperatures the superconducting electrodes induce superconductivity in the topological insulator by the proximity effect, with a finite Josephson current observed across a sufficiently narrow gap.

Transport and RF-Reflectometry Measurements of CMOS Nanodevices
Pioneering work on semiconductor quantum dots has shown that quantum dots are promising candidates as a building block (qubit) for quantum information and computation. Quantum dots are quasi-zero-dimensional nanostructures which can confine single electrons, whose spin or charge degree of freedom can then be used to represent quantum bits (qubits). Quantum computing approaches based on semiconductors can build upon mature micro/nano-fabrication technologies, which will be invaluable in scaling up to a large number of reproducible qubits with practical yields and integrated electronics. As part of the classical information technology industry, CMOS transistors have reached sufficiently small feature sizes that quantum effects can begin to play a dominant role. This motivates the exploration of quantum effects in such transistors fabricated using CMOS processes.
