In this talk, I will describe some recent work from my laboratory exploring quantum phases in scotch-tape created atomically thin materials. First, I will describe experiments on bilayer MoTe2, where we observe a gate-tunable superconductor that is also a ferroelectric. I will show that electron-hole nesting in this material plays a key role in the observed superconducting properties. Next, I will describe experiments on point contacts in 2D semiconductors. I will show that in the presence of strong electron interactions, spin-degeneracy can be spontaneously broken in the limit of quantized transmission. Finally, I will discuss recent experiments on moiré tuned twisted 2D semiconductors, where we see clear evidence for the formation of itinerant metallic magnets driven by proximity to a van Hove singularity.
