1. A graphene solar cell driven nanopropulsion MEMS component made by semiconductor techniques and that can travel at the speed of light  

2. Introduction (overview)
Purpose of the lecture
A narrowing of the theme
Four part component. All will be thoroughly explained individually

3. PART 1: Nanopropulsion

4. Traditional Propulsion
Based on momentum
P = mv
Rocket thrusts forward by rearward ejection of fuel
Total mass is constant
But mass of rocket decreases
F = - v_ex (dm/dt) is the thrust of the rocket

5. Nanopropulsion – principle of operation
Extreme properties seen at critical sizes
Monolayer Graphene deposited by MBE or ALD
An ideal efficient field emitter
Could be comparable to a bulkmaterial
Furthermore could lead to millions of nanoreactors in system
Other materials are also possible of course

6. PART 2 :Graphene solar cell
To collect solar energy
Has considerable higher efficiency than silicon
Would cladd the engine
Constant replenishment
The energy could either be charged in a capacitator
Or directly to the nanorecactor
Built by traditional semiconductor CMOS technology
PART 2 :Graphene solar cell

7. PART 3: Microelectricalmechanical system (MEMS)

8. Function: Alerting and potentially creating ions for thrust
Thermal sensing
Thermal expansion
Varies for materials
Must be a monolayer
Parallell plate conductance sensing
Different advantages
Two c. plates with a dielectric layer between

9. PART 4: Light speed
Difficult to comprehend without papers in front of you (will publish later this summer probably)

10. Final experimental design

11. Semiconductor techniques used
- Molecular Beam Epitaxy to deposit graphene
MEMS part based on traditional CMOS
Optical lithography by resist to make nanoreactors
Ion technology present, but not in the form of ion implantation :D
