This behavior is typical, for example, of ferroelectric materials.
First of all, the thickness of the materials composing the stack was chosen in order to match the static performance of the proposed device with a reference one, with a standard gate oxide of 50 nm, typical thickness for a 1.2 kV SiC MOSFET.

Introduction It is necessary to transport some granular materials or semi-liquid chemical raw materials in some actual projects.
But in the process of transportation of these raw materials the traditional lorry without case cover might cause the splash of the chemical raw materials, resulting in waste and danger [1].
· In order to prevent the materials from spilling, a case cover is needed [4]

(1) For practical calculations of thermal conductivity stone materials and light concretes on natural porous aggregates the following formula is proposed: (2) When determining the thermal conductivity of building materials, it is recommended to use the following dependencies: (3) , (4) where the coefficient k takes values depending on the dimension (k = 1.164 for the dimension W/m∙oС.
To meet the energy conservation conditions for KBR conditions, R0 = 2.54 m2∙oС/W further development of a single-layer panel using local materials at this stage is considered impractical.

These smart materials include shape memory alloy (SMA), piezoelectricity, electroactive polymers (EAPs) and etc.
Ionic polymer metal composites (IPMC) is a kind of EAPs and a particularly promising class of actuator materials for underwater microrobots [2-7], since it produces large bending motions under low voltages (1 - 2 V), works well in water and other fluids, and is flexible and biocompatible.
