“…The set-and-forget nature and the application of low voltage input signals greatly reduce the power dissipation of the DM, because no constant HV-input or high update frequency is required to avoid pixel drift as a result of charge leakage of the holding capacitor 14 when high pixel number DMs are considered. This is not only advantageous from an operational point of view but it also limits thermoelastic deformations in the imaging system and eliminates pixel instability as a result of noise in the driver electronics.…”

We present the conceptual design and initial development of the hysteretic deformable mirror (HDM). The HDM is a completely new approach to the design and operation of deformable mirrors (DMs) for wavefront correction in advanced imaging systems. The key technology breakthrough is the application of highly hysteretic piezoelectric material in combination with a simple electrode layout to efficiently define single actuator pixels. The set-and-forget nature of the HDM, which is based on the large remnant deformation of the newly developed piezomaterial, facilitates the use of time division multiplexing to address the single pixels without the need for high update frequencies to avoid pixel drift. This, in combination with the simple electrode layout, paves the way for upscaling to extremely high pixel numbers (≥128 × 128) and pixel density (100∕mm 2 ) DMs, which is of great importance for high spatial frequency wavefront correction in some of the most advanced imaging systems in the world.

“…This imposes a serious limitation on the desired integrated density and leads to poor performance in the thin-film transistor-based NVMDs [19]. In order to fulfill the particularly required performance such as retention time, endurance, response time, and/or power consumption, plenty of nanomaterials and alternative technologies have been utilized to enhance the integrated density and performance, which open a route to overcome the scaling limitations and economic challenges encountered in the current silicon industry [20-24]. In this survey, we summarize the current researches on fabricating a promising nano-FeFET.…”

In the past decades, ferroelectric materials have attracted wide attention due to their applications in nonvolatile memory devices (NVMDs) rendered by the electrically switchable spontaneous polarizations. Furthermore, the combination of ferroelectric and nanomaterials opens a new route to fabricating a nanoscale memory device with ultrahigh memory integration, which greatly eases the ever increasing scaling and economic challenges encountered in the traditional semiconductor industry. In this review, we summarize the recent development of the nonvolatile ferroelectric field effect transistor (FeFET) memory devices based on nanostructures. The operating principles of FeFET are introduced first, followed by the discussion of the real FeFET memory nanodevices based on oxide nanowires, nanoparticles, semiconductor nanotetrapods, carbon nanotubes, and graphene. Finally, we present the opportunities and challenges in nanomemory devices and our views on the future prospects of NVMDs.
