What is it about?
Electrons travel differently through chiral molecules depending on their spin, known as Chirality-Induced Spin Selectivity. However, this effect strongly depends on the interaction the molecules have with the electrodes that the molecules are attached to. This interaction will cause a temperature dependence of electrons' transport which explains experimental results much better than other theories.

Why is it important?
The Chirality-Induced Spin Selectivity effect is important because it has potential applications in areas such as spintronics. Understanding the theory behind it is critical to be able to use it in applications.
Perspectives
Writing up this article was fun. We shed light on how temperature influences the behavior of electrons in chiral molecules (CISS effect) and challenges previous interpretations with new insights from the spinterface model. It reveals that the CISS effect intensifies as temperature drops. I am curious, can the increased CISS effect be harnessed in low temperature quantum-spintronics application?
