TESTE DEIN WISSEN

What are free valence electrons ?

Lösung anzeigen
TESTE DEIN WISSEN

The concept veleny describes the properties of stable and unstable atoms. Unstable atoms are missing an electron in their shell and will try to get one to reach an stable state. This means that electrons can move from one place to another to connect with an element that is missing on in its shell. 

First shell = max 2

Second shell = max 8 electrons 

--> will always try to get the max possible

Why is an mechatronics system always a combination out of multiple disciplines? 



Lösung anzeigen
TESTE DEIN WISSEN

The different systems are dependent by each other and make no sense singaly. 


Software --> source code useless without system

Sensors --> detects physical parameter, useless without transformation in computable signals 

Actuators --> perform action based on inputs, requires control

Out of which components is mechatronics formed?

Lösung anzeigen
TESTE DEIN WISSEN

Meachtonics is composed out of:

Mecha : mechanism, mechanics 

tronics : electronics 

and the integration of computer control


Engineering design out of:

Mechanical, electronical and computer systems.

What are the abilities of a semiconductor device? 

What are the properties? 

1. The structure of a semiconductor s material needs to be considered. 

2. Free electrons enables current flow 

3. The number of charge carriers depends on the amount of thermal energy presente in the structure. 

4. Many semiconductors properties are functions of temperature.

TESTE DEIN WISSEN

Semiconductors are out of materials consisting from elements out of the group 4 and have the electrical paperbilities falling between conducting and isolating. (Silicium)

Higher temperature = higher resistance 

--> often used for thermo things

How is a analog electronic system defined? 


Lösung anzeigen
TESTE DEIN WISSEN

A analog electrical system has other than an electrical system only two possible variable systems/states that can be represented. Analog describes the proportional relationship between a signal and voltage current.

TESTE DEIN WISSEN

It is defined on the number of protons.

The number of electrons can varies  

    - State of the electronic charge

What does recombination mean in combination with semiconductor? 

Lösung anzeigen
TESTE DEIN WISSEN

It is an additional phenomena that reduces the number of charge carriers in a semiconductor.

The number of free electrons available for a given material is called the intrinsic condition
