General Questions and Answers / question related to simulation

« on: September 7, 2012, 10:12 »

Dear everyone,

1. I want to see the bonding strength between

                       Base Material: Tungsten Carbide

                       Bonding with: Ni-TiC Composite or Al- TiC

 

2. How can I make the electrodes of different shapes as shown in attachment?

 

3. The total energy as function for distance between the electrodes. It’s calculate for optimize the two probe device. Pls send me code for this       problem?

 

4. Is it possible to be calculated the light property like absorption coefftient and other like property?

 

5. I have seen that every I-V results of device configuration in atk are linear response. My question is how I can see the P-N DIODE (I-V) forward bias char. In addition, I want to see C-V curve. This is possible in atk.

 

6.  Can we make the organic material based design like as OTFT, OLED in atk?

thanks & regards

Dear Quantum Wise,

P's suggested me how i can  optimize distance b/w electrode  with out change the scattering and crystal  size. i have read answer of these question on forum but i'  could not understand the answer.
 
pls send me code for calculating  total energy function of distance b/w electrode .

General Questions and Answers / mterial and device

« on: August 23, 2012, 08:24 »

Dear QuantumWise

Please give me answer of these question???

1.how could I prepare electrodes of various metals like Silver, Platinum, Lithium,Aluminium etc. It can be graphene ot CNT but I am interested in Metallic electrodes only.

2.how can I make the electrodes of different shapes

3.I was calculating the transport properties of CdS-CdTe-CdS nanowire, I could not get to convergence for most of the bias voltages in the range of -3 V to 3 V. I got the message that convergance could not be achieved after possible 199 steps. Please find the solutions and let me know those.

thanks & regards

Dear Quantum wise,
 
i am new in quantum Wise ATK so that i have alot question in  atk.

 can u give me  answer of these question.

1. chemical potential
2. P DOS(PROJECT  DOS)
3. Bloch state
4. how many no. of electrode on device configuration
5. we can calculated non linear i-v char. of  any diode (p-n , tunnel diode)
6.diff. b/w bottom and top approach or atk depend on which approach.
7.you have any manual of diode configuration like as - P-N DIODE.
8.is it possible to include new molecule in  vnl database 
 
Thanks &  regards

Dear quantum wise,
my quation is ,short description on these question .
1.chemical potential
2. p dos
3. bl ouch state
5. any tutorial provide of non line  graph of device configuration.
8. you can provide ,any process of include new molecule in VNL database by GUI Base not python code.
4. how many type make terminal device in atk.
6. MY question is ATK depend on which approach either bottom approach or top up approach .also describe both approach.

thanks & warms regard
