  The isolation of air-sensitive two-dimensional (2D) materials and the race to
achieve a better control of the interfaces in van der Waals heterostructures
has pushed the scientific community towards the development of experimental
setups that allow to exfoliate and transfer 2D materials under inert
atmospheric conditions. These systems are typically based on over pressurized
N2 of Ar gloveboxes that require the use of very thick gloves to operate within
the chamber or the implementation of several motorized micro-manipulators.
Here, we set up a deterministic transfer system for 2D materials within a
gloveless anaerobic chamber. Unlike other setups based on over-pressurized
gloveboxes, in our system the operator can manipulate the 2D materials within
the chamber with bare hands. This experimental setup allows us to exfoliate 2D
materials and to deterministically place them at a desired location with
accuracy in a controlled O2-free and very low humidity (<2% RH) atmosphere. We
illustrate the potential of this system to work with air-sensitive 2D materials
by comparing the stability of black phosphorus and perovskite flakes inside and
outside the anaerobic chamber.
