pangru said:What does underdoped cuprates mean?
As I guess cuprate is underdoped when hole concentration is less then optimal doping.
Is it correct?...

Underdoped cuprates are a type of high-temperature superconducting material that is composed of copper and oxygen atoms. They are called "underdoped" because they have a lower concentration of charge carriers (electrons or holes) than is required for optimal superconductivity.
Underdoped cuprates exhibit superconducting properties at much higher temperatures than regular superconductors, which require very low temperatures (near absolute zero) to function. They also have a more complex crystal structure and involve interactions between electrons and the copper and oxygen atoms, making them more difficult to understand and control.
Underdoped cuprates are significant because they have the potential to revolutionize technology by allowing for more efficient and practical superconducting devices. They also provide insight into the nature of superconductivity and the behavior of electrons in complex materials.
Underdoped cuprates are studied using a variety of experimental techniques, such as X-ray diffraction, neutron scattering, and electron microscopy, to analyze their structure and behavior at the atomic level. They are also studied through theoretical models and simulations to better understand their properties and potential applications.
One of the main challenges in understanding underdoped cuprates is their complex crystal structure and the interactions between electrons and atoms. Another challenge is the difficulty in synthesizing high-quality samples for study. Additionally, the exact mechanisms that lead to high-temperature superconductivity in underdoped cuprates are still not fully understood, making it a subject of ongoing research and debate.
