define the following terms as they pertain to semiconducting materials: intrinsic, extrinsic, compound, elemental. provide an example of each.

Answers

Answer 1

The definition of intrinsic is a pure semiconducting material; extrinsic is a semiconducting material that has intentional impurities added; compound is a semiconducting material made up of two or more different elements; elemental is a semiconducting material made up of a single element.

Semiconductors are solid materials which have a resistivity value between 10-2 – 109 Ω.cm.  

The following is the complete information of types of semiconducting materials with each example:

Intrinsic: Refers to a pure semiconducting material, meaning it contains no intentional impurities. Intrinsic materials have a specific number of free electrons and holes that are determined by the temperature and bandgap energy of the material. An example of an intrinsic semiconductor is pure silicon.

Extrinsic: Refers to a semiconducting material that has intentional impurities added to it in order to modify its electrical properties. These impurities, known as doppants, can either introduce additional free electrons (n-type) or holes (p-type) into the material. Examples of extrinsic semiconductors include n-type silicon dopped with phosphorus, or p-type silicon d0pped with boron.

Compound: Refers to a semiconducting material made up of two or more different elements, typically from groups III and V or II and VI in the periodic table. Examples of compound semiconductors include gallium arsenide (GaAs) and indium phosphide (InP).

Elemental: Refers to a semiconducting material made up of a single element. Silicon is the most commonly used elemental semiconductor, but other examples include gerrmanium (Ge) and carbon (in the form of diamond or graphene).

How a car break works?

The break system of a car is composed by several items that are always working together to slow down and bring a vehicle to a complete stop. It also has the function of keeping the car stationary when it is parked. In general, this system has two manual activation modes: the lever and the pedal, with the exception of vehicles adapted for people with disabilities.

Most vehicles today use the disc brake system. Disc brakes work by using pads, which are held inside a hydraulic caliper, receiving pressure to brake. Such pads generate friction on a disc, which makes the vehicle stop permanently.

The drum brake is another type, being older and dependent on the famous linings to cause friction in the wheel and stop the vehicle. A hydraulic cylinder makes the plies move inside the drum, which is a hollow part fastened with screws and attached to the wheels. This type of brake is on the rear wheels, for the most common models.

Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt.% at a position of 4 mm into an iron-carbon alloy that initially contains 0.10 wt.% C. The surface concentration is to be maintained at 0.90 wt.% C, and the treatment is to be conducted at C. Use the diffusion data for -Fe in Table 5.2

Answers

The carburizing time necessary to achieve a carbon concentration is 31.35 hours

How to find the Carburizing Time?

To determine the carburizing time necessary to achieve the given carbon concentration, we will use the equation:

(Cs - Cx)/(Cs - C0) = ERF(x/2√Dt)

where;

Cs is Concentration of carbon at surface = 0.90

Cx is Concentration of carbon at distance x = 0.30

Distance x = 4 mm = 0.004 m

C0 is Initial concentration of carbon = 0.10

ERF() = Error function at the given value

D = Diffusion of Carbon into steel

t = Time necessary to achieve given carbon concentration ,

Thus, plugging in the relevant values gives;

(Cs - Cx)/(Cs - C0) = (0.9 - 0.3)/(0.9 - 0.1)

= 0.6/0.8 = 0.75

now, ERF(z) = 0.75 and as such using ERF table, we can say that;

Z = 0.814. Thus;

(x/2√Dt) = 0.81

Using the table of diffusion data, we have;

At a temperature of  (1100°C) or 1373 K, we have;

D = 5.35 × 10⁻¹¹ m²/sec.

Calculating the carbonizing time by using the equation z = (x/2√Dt);

where;

t is carbonizing time

Thus;

0.814 = (0.004/(2 × √5.35 × 10⁻¹¹ × √t))

0.814 = 0.004 /(1.4628 × 10⁻⁵ × √t)

0.814 × 1.4628 × 10⁻⁵ × √t = 0.004

1.19072 × 10⁻⁵ × √t = 0.004  

√t = 0.004/(1.19072 × 10⁻⁵)

√t = 335.93

t = 112848.96 seconds

Converting to hours gives;

t = 112848.96/3600

t = 31.35 hours

Therefore, the carburizing time necessary to achieve a carbon concentration is 31.35 hours

Answers

The time at which the acceleration is zero is given as 4.66 seconds

How to solve for the time

First we have to solve for the velocity. To do this, we would have to take the derivative.

[tex]s = e^-0.5t (3 t - 2)[/tex]

Then velocity =

[tex]ds/dt = e^-0.5t (4 - 1.5 t)[/tex]

The acceleration can be gotten by finding the second derivative

[tex]a = dv/dt = e^-0.5t (.75 t - 3.5)[/tex]

To find t at acceleration = 0
