we use polysislicon instead of metal because polysilicon has the self aligned property.
The Golden Gate Bridge connects San Francisco and Marin County. It is an iconic suspension bridge that spans the Golden Gate Strait, the entrance to San Francisco Bay from the Pacific Ocean.
Iron corrodes, "rusts" due to the reaction with oxygen principally that dissolved in water. The obvious thing is to coat the iron with paint to prevent water coming in contact. Paint usually requires a priming coat which is designed to give good adhesion to the metal surface, followed by other coats on top Another strategy is to coat the iron with a metal such as zinc. This has a dual effect not only physically coating the iron but as zinc is more reactive it forms a sacrificial anode. Lots of technology here, zinc can be electrochemically coated "galvanised", spay coated and hot dipped. Look up sacrificial anode - ships use these sailing types call them "zincs" which protect the hulls from corrosion, these would work on a gate!
The storage element of EEPROM is a floating gate transistor. This transistor can trap or release electrons, which alters the conductivity of the transistor and determines whether a binary value (0 or 1) is stored in a specific memory cell.
Silicon oxide is used in MOSFET gate insulation because it is a good insulator with high dielectric strength. It allows for efficient control of current flow between the source and drain by applying a voltage to the gate. Additionally, silicon oxide can be easily integrated into the existing silicon manufacturing process, making it a cost-effective choice for MOSFET fabrication.
Golden Gate Park in San Francisco features a variety of landforms, including hills, meadows, lakes, and gardens. The park's topography includes areas with gentle slopes as well as steeper terrain, offering visitors diverse landscapes to explore. The park also has man-made features such as trails, roads, and bridges that complement its natural landforms.
aluminum was used earlier,, now adays polysilicon is used
Because of threshold voltage reduction of MOSFETs. Comparing with metals for the gate of MOSFETs, polysilicon has small work function difference with the substrate silicon of MOSFETs.
gate is made out of metal
One can purchase a metal gate several places. For example, one could purchase a metal gate at an online retailer, such as Amazon, or eBay. One could also buy a metal gate at a local home improvement store.

Because the gate terminal should highly resistive..silicon dioxide has high resistance and hence gate current is very very low...

One effective way to cover a metal gate for privacy is to install a privacy screen or fence panels that are specifically designed to block the view. These can be made of materials such as wood, vinyl, or metal and can be attached directly to the gate for added privacy.
because long ago, the ancient time... Metal had been invented and everything was made out of it when they discovered it! A Baton was an accident and wasn't supposed to be made... They were making an alternative for a gate/fence, and ended up with a Baton instead.
a gate?
you can pay to buy materials
