The research proposes experiments on the electronic and optical properties of high temperature superconducting compounds such as strontium- and zinc-doped lanthanum cuprates. The insulating side of the metal-insulator transition will be studied to ascertain the precursor properties ultimately leading to superconductivity for large enough values of the doping. Experimental techniques to be employed include photoconductivity and photoluminescence, Hall effect and magnetoresistance measurements. The overall objective is to better characterize the semiconductor-to-metal transition as the carrier density is increased.

本研究提出了对高温超导化合物（如锶和锌掺杂的铜酸镧）的电子和光学性质进行实验。将研究金属-绝缘体过渡的绝缘面，以确定在足够大的掺杂值下最终导致超导的前驱体性质。实验技术包括光导和光致发光，霍尔效应和磁阻测量。总体目标是随着载流子密度的增加，更好地表征半导体到金属的转变。
