Substrate removal and capillary bonding of a quantum beat sample
説明
The multiple quantum well (MQW) structure designed to utilize light hole (lh) and heavy hole (hh) energy states for producing coherent excitation of lh and hh excitons and resulting in radiation in the THz range of frequencies. Energies of states can be tunable with applied electric bias, resulting in a tunability of the radiation frequency. In our work, we aim to produce room temperature tunable THz radiation by optically exciting the QB sample using continues wave (CW) laser sources. In order to maximize the incident power upon the sample, and simplify the collection of the THz radiation, a structure, which has had the substrate, removed by using different method as thinning and wet etching, and capillary bonded to diamond is required.
