Why ion implantation is necessary?
Ion implantation is necessary in semiconductor manufacturing to precisely introduce dopant atoms into the crystal lattice of a semiconductor material, which helps modify its electrical properties. This process allows for precise control of the dopant concentration and profile, enabling the creation of specific device characteristics such as the conductivity type and doping level. Ion implantation is also used for creating shallow junctions in transistors and optimizing device performance.
What is the difference between diffusion potential and nernst potential?
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
What is the effect of the chloride ion concentration on its rate of diffusion in agar?
Increasing the chloride ion concentration will generally increase its rate of diffusion in agar. This is because a higher concentration gradient will drive chloride ions to diffuse more rapidly through the agar medium. Ultimately, diffusion rate is directly proportional to the concentration gradient of the solute.
What are the advantages and disadvantages of common names of polyatomic ions?
Advantages: Common names are easier to remember and recognize compared to chemical nomenclature. They provide insight into the composition or behavior of the ion. Disadvantages: Common names can vary between regions or textbooks, leading to confusion. They may not always clearly indicate the ion's composition.
Factors affecting gas diffusion?
stomatal movements( it depends on light, temperature, condition of the plant, glucose & sucrose concentrations, ion concentrations....) , intra cellular gaps in spongy paranchyma, atmospheric & plant pressure, amount of gases in the atmosphere, ...... are the factors which effect the gas exchange.
Difference between Diffusion and ion implantation?
diffusion is high temperature process while ion implantation is low temperature process
What is the difference between diffusion and ion implantation?
Diffusion is the mixing of two materials by the natural movement of the particles.Implantation is a forced action for the introduction of an item (or partcle) in other object (material).
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
What are the advantages of thermal cracking over catalytic cracking?
Carbonium ion process
What are the advantages of catalytic cracking over thermal cracking?
Carbonium ion process
How is facilitated diffusion similar to diffusion ion channels?
Facilitated diffusion and diffusion ion channels both involve the movement of substances down a concentration gradient without requiring energy input. However, facilitated diffusion involves the assistance of carrier proteins to transport specific molecules, while diffusion ion channels are specialized proteins that form pores in cell membranes for specific ions to pass through.
What is a dimer in ion implantation?
In ion implantation, a dimer refers to two atoms that are implanted simultaneously into a target material. This can be beneficial for certain applications where the presence of two atoms together can create specific interactions or properties in the material. Dimer implantation can be used to tailor the material's properties by controlling the concentration and distribution of the two types of atoms.
Is facilitated diffusion ion channels an active or passive transport?
passive
What substance crosses the cell membrane by facilitated diffusion?
a sodium ion

Ions diffuse across membranes down their what?
Its an active transport and use sodium channel generally _____ Diffusion is itself a pathway of travel across a cell membrane. Diffusion can be "simple diffusion" which is simply an ion moving across the membrane anywhere, or "fascilitated diffusion", where an ion moves across the membrane in a specific channel. Either way, diffusion involves the movement of that ion along its concentration gradient and requires no energy. Active transport is not the same as diffusion. Active transport requires energy.
How does sodium ion molecule move into the cell through cell membrane?
Through diffusion.
