Hardware for Quantum Research
We make research instruments for Quantum Research including but not limited to Nanoelectronics, Nanophotonics and Nanomagnetism. We provide the experimental environment [cryogenic/ magnetic/electrostatic], characterization tools [electrical probing, voltage sources] or sample manipulation tools such as 2D Transfer Systems for making 2D hetero-structures.
Dr. Vidya Kochat Assistant Prof. Material Science IIT Kharagpur
We have been able to fabricate a lot of 2D hetreostructures with good precision and control using the 2D Transfer System by Cryonano. The fine angle adjustment has also been very helpful in making twisted bilayers of graphene and various other TMDCs. The temperature control is also good and optics is top class.
The visualization of the flakes during the transfer is excellent and hence we are able to fabricate 2D heterostructures with high degree of precision. Recently a journal article has been published in Journal of Applied Physics. 2023;133(11). where Cryonano transfer system was used to make heterostructures.
Dr Biswajit Karmakar Associate Prof, Saha Institute of Nuclear Physics, India
We have been using the 16-bit digital to analog isolated voltage source (IVS) from Cryonano for quite sometime now and it has become a mainstay for our lab. It has four truly bipolar +/- 10 V output that is controlled by Labview. We are extensively using the IVS for our ongoing research work for mainly Gate Voltage Control of our multi-terminal quantum hall Systems, Gate Voltage Control on graphene devices and I-V spectroscopy of fractional quantum hall systems.. We have carried out several experiments and published two papers (Phys. Rev. Lett. 125, 076802 – Published 12 August 2020; Phys. Rev. B 104, 085304 – Published 9 August 2021).

a) A glimpse of the new 2DTS b) A closer look of the transfer mechanism
2DTS is suitable for the precise fixed-point transfer of single-layer materials such as graphene, molybdenum sulfide, and black phosphorus, as well as the preparation of multi-layer van der Waals heterojunctions while visualization of low-dimensional material transfer. The transfer system consists of a microscopic system, a three-axis transfer stage, and a vacuum puck with an integrated heated sample stage. The target substrate stage can be rotated at a large angle in the plane, which is a powerful tool for studying the characteristics of heterojunctions, the breaking of space inversion symmetry, and the influence of different stacking methods of two-dimensional materials
High stability, high-precision mechanical design and high-quality microscopic imaging system enables the precise transfer of tiny samples less than 5 μm . 2DTS integrates the whole process of device preparation such as observation, transfer, imaging and recording.
