Spatial period-multiplying instabilities of hexagonal Faraday waves [PDF]
, 2000 A recent Faraday wave experiment with two-frequency forcing reports two types of `superlattice' patterns that display periodic spatial structures having two separate scales. These patterns both arise as secondary states once the primary hexagonal pattern

Performance Evaluation of Type-II Superlattice Devices Relative to HgCdTe Photodiodes
IEEE Transactions on Electron Devices, 2022 At present stage of infrared (IR) detector technology, two material systems, type-II superlattices (T2SLs) and HgCdTe ternary alloys, are used in fabrication of both mid- and long-wavelength IR arrays. The proposal of a new metric, the so-called “Law 19,”

Thiol passivation of MWIR type II superlattice photodetectors [PDF]
SPIE Proceedings, 2013 Poor passivation on photodetectors can result in catastrophic failure of the device. Abrupt termination of mesa side walls during pixel definition generates dangling bonds that lead to inversion layers and surface traps leading to surface leakage currents that short circuit diode action. Good passivation, therefore, is critical in the fabrication of
