A gate or gateway is a point of entry to or from a space enclosed by walls. The word derived from old Norse "gat" meaning road or path; But other terms includ yett and port. The concept originally referred to the gap or hole in the wall or fence, rather than a barrier which closed it. Gates may prevent or control the entry or exit of individuals, or they may be merely decorative. The moving part or parts of a gateway may be considered "doors", as they are fixed at one side whilst opening and closing like one.A gate may have a latch that can be raised and lowered to both open a gate or prevent it from swinging. Locks are also used on gates to increase the security. Larger gates can be used for a whole building, such as a castle or fortified town. Actual doors can also be considered gates when they are used to block entry as prevalent within a gatehouse. Today, many gate doors are opened by an automated gate operator.
I am trying to simulate a Gate-All-Around FET in Silvaco TCAD for my thesis but I can't figure out how to add HZO (Hf0.5Zr0.5O2). I would really appreciate it if anyone could help me with the code for HZO or help me in any other way.
Thank you.

I got an expression for the angle taking that initially the gate is closed, so the gate has h, W and L as their dimensions. So there is a surface integral to find the resultant force applied on the gate, using the...
As you can see this is perceptron training rule. I want to learn how it can't implement xor. After 1 epoch/iteration, I get w1=0, w2=0,b=0. does this keeps on repeating? Anyone can implement this algorithm to code in python? Would be nice to see what happens in long run.
First the hybrid model, I assume the capacitor works as a short circuit regarding the altern current:
$$A_V=\frac{v_o}{v_i}$$
$$v_i=-v_{GS}$$
$$v_o=-i_LR_L$$
$$i_L=g_mv_{GS}+\frac{v_{DS}}{r_d}$$
Now I use the Kirchhoff's law to get $v_{DS}$. I consider this close loop:
$$-v_i-v_{DS}+v_o=0$$...

Hi, not really a homework question just a quick question regarding FET-transistor. If the gate potential is -4V does that mean that in the figure below that uGS is -4V. If not, what does it mean and how do you use it in a bigger circuit problem?

I'm in the process of repairing a wooden gate and would like to replace the wooden posts with metal ones, to help avoid the amount of sag over time. Both the gates are 59 wide by 50 height weighing about 25-50 pounds each(I don't have a scale to weigh it) made from pressure treated wood.

I am interested in using GaN MOSFETS for my circuit and I'm looking at the EPC2012C. I'll attach the datasheet here. I noticed that it calls for a -4 Vgs. If my driver only goes to 0 V, will this cause a problem? What is the benefit in driving negative if it's not required?

Why is it that the smaller the gate length, the higher the max operating frequency becomes? In particular, I think I saw somewhere that a 6 um gate length, seems to limit ICs to 100kHz, where as 1 um is around 1MHz (all rough ball bark numbers, and can be persuaded otherwise). Was wondering if...

I thought that the upward/vertical torque due to the cord might be T*sin 30 deg * sqrt (4^2 + 2^2). Then this would have to equal the weight of the gate times the distance (700 N * 2 m). This gives a tension force of 626 Newtons but it's not the right answer. I don't even know what the lever arm...

Hello,
I don't know much about logic gates and how they work.
I was wondering if this (Image) can work. (Is something like this possible?)
The idea is that if we have logic 1, AND gate gives 1 while NOR gives 0. And vice versa.

I'm trying to figure out how you would actually measure the result of a quantum gate. For example, suppose I build a Hadamard gate by using a beam splitter.
